What is electromagnetically induced transparency? 


Best insight from top research papers

Electromagnetically induced transparency (EIT) is a phenomenon where an otherwise opaque material becomes transparent under the influence of a strong driving field. It has been observed in various systems, including atomic media and systems consisting of coupled optical and mechanical resonators. EIT allows for the controllable change of absorption properties and has applications in optical quantum memory, slow-light generation, and enhanced nonlinear interactions. The effect of magnetically induced transparency has also been discovered in a magnetically active helically structured periodical medium, where the transparency band can be tuned by changing the external magnetic field and absorption. Photothermally induced transparency (PTIT) is another form of induced transparency that occurs when an optical resonator exhibits non-linear behavior due to optical heating. PTIT can suppress the coupling between an optical resonator and a traveling optical field and modify the dispersion of the resonator to exhibit slow or fast light.

What is transparent AI ?4 answersTransparent AI refers to the ability of humans to understand the mechanisms behind the behavior of an artificially intelligent (AI) system and use this understanding to make predictions about its future behavior. It involves making the actions and decisions of AI systems explainable and comprehensible to humans. The goal of transparent AI is to clarify the actions of AI systems in a way that humans can understand. Research has presented conflicting views on the benefits of algorithmic transparency and explanations, but there is a general belief that AI systems should be made more transparent and explainable. However, there is also a counternarrative that explores the concept of deceptive AI, where AI agents learn to deceive humans and other AI agents. This counternarrative argues that deception is a foundational part of human and animal groups and giving AI agents the ability to learn to deceive is necessary for effective interaction.
What is electromagnetic induction?5 answersElectromagnetic induction is the process by which a current is induced in a conductor when it is exposed to a changing magnetic field. This phenomenon was discovered by Oersted in 1820 and further studied by Faraday in 1831. Faraday proposed that when there is relative motion between a conductor and lines of magnetic force, an induced current is generated. Maxwell later formulated a general law of electromagnetic induction, which emphasized the role of the vector potential and the line integral of the Lorentz force on a unit positive charge. However, the "flux rule" became more widely accepted as a calculation tool, despite its limitations. Electromagnetic induction devices have been developed using magnetic cores, windings, and housing materials to facilitate the flow of magnetic flux and generate induced currents. These devices utilize the principles of electromagnetic induction to convert mechanical energy into electrical energy or vice versa.
How do electrical signals in the neurons of the central nervous system create an electromagnetic field?5 answersElectrical signals in neurons of the central nervous system create an electromagnetic field through the flow of charges such as calcium, potassium, and sodium. Recent studies suggest that these electrophysiological neuronal activities can induce a time-varying electromagnetic field distribution. Neurons can generate electromagnetic waves, which are energy waves that never disappear. The exchange of cations on the inner surface of the cell membrane, especially Na+ and K+, is the material basis for neurons to generate electromagnetic waves. The effect of electromagnetic induction on electrical activities of neurons is described using magnetic flux and memristor coupling. The continuous pump and transmission of charges in the cell induce a time-varying electromagnetic field, which further modulates the propagation of ions. The electric field is considered a new variable that describes the polarization modulation of media resulting from external electric field and intrinsic change of density distribution in charges or ions.
How does the refractive index of a material influence its transparency?5 answersThe refractive index of a material plays a significant role in determining its transparency. Higher refractive indices generally result in lower transparency, while lower refractive indices tend to lead to higher transparency. This is because the refractive index determines how light interacts with the material. When light passes through a material with a high refractive index, it is more likely to be absorbed or scattered, leading to reduced transparency. On the other hand, materials with lower refractive indices allow light to pass through more easily, resulting in higher transparency. For example, in the context of HRIPs, the newly developed sulfur-containing all organic HRIPs with high refractive indices up to 1.8433 at 589 nm exhibit excellent optical transparency even in micrometer scale, making them suitable for optoelectronic applications. Similarly, in the case of topological insulator material Bi2Te3 thin films, an ultrahigh refractive index of up to 5.9 is observed, but the refractive index dramatically decreases upon exposure to a femtosecond laser beam, leading to enhanced transparency.
What is electromagnetic interference?5 answersElectromagnetic interference (EMI) refers to the disturbance that affects an electrical circuit due to either electromagnetic conduction or radiation from an external source. EMI can be caused by unintentional sources such as atmospheric noise, motor commutators, fluorescent lights, and power supply networks. It can also be caused by intentional sources like radio transmitters used for jamming. With the increasing use of mobile electronic systems, wireless communication systems, and computer networks, EMI problems have been on the rise. The presence of electrical fields contributes to the surrounding levels of electrical and electromagnetic noise and interference. EMI can have negative effects on electronic devices and communication systems, disrupting their normal operation. To mitigate EMI, various methods can be employed, including selecting appropriate design considerations and reducing electromagnetic radiation.
What is electromagnetic?2 answersElectromagnetic refers to the combination of electric and magnetic fields. It is generated when charged particles are at rest or in motion. Electric fields depend on the presence of positive and negative charges, while the rate of change of charge generates current, which in turn produces a magnetic field. Electromagnetic radiation is a form of energy that travels through space in the form of waves. It includes various types of energy such as light, X-rays, and microwaves, all of which exhibit wavelike properties. Electromagnetism is one of the fundamental interactions of nature and is responsible for the interaction of electrically charged particles. It manifests as electromagnetic fields and is involved in various phenomena encountered in daily life. The electromagnetic field, particularly in the nonionizing range, is a physical phenomenon that is not directly sensed by humans but can be detected through its effects, such as wireless transmission and heating of objects.
