What is electromagnetic waves?4 answersElectromagnetic waves are a form of energy characterized by oscillating electric and magnetic fields, with individual packets known as photons. These waves can transmit both information and energy wirelessly, as discovered by scientists like Maxwell, Faraday, and Ampere. They exhibit wavelike properties and consist of oscillating electric and magnetic fields perpendicular to each other. Electromagnetic radiation spans a wide range of energies, from X-rays and gamma rays to ultraviolet, visible light, and radio waves. Understanding wave propagation principles, atmospheric windows, and wave interactions with different media is crucial in comprehending electromagnetic wave behavior. Overall, electromagnetic waves play a fundamental role in various aspects of daily life, from wireless communication to medical diagnostics and beyond.

How are used Bessel beams in laser material processing?5 answersBessel beams are used in laser material processing for various applications. One application is the generation of structured laser beams with elongated focal areas and self-healing properties, which can be achieved using higher-order Bessel beams formed by axicons, spiral phase plates, or phase masks. These beams have advantages in laser micromachining of transparent materials due to their small central peak and elongated focal region. Another application is the generation of non-diffracting beams using femtosecond direct laser writing based on two-photon polymerization, which allows for the conversion of ideal Bessel beams into polymer phase plates. Additionally, high-order vector Bessel-Gauss beams generated using geometric-phase-based optical elements have been used for laser micromachining of transparent materials, creating three-dimensional tubular structures and testing etch selectivity. Alternative methods for generating Bessel beams include diffractive optical elements, sub-wavelength metasurfaces, and liquid crystals, which provide more flexibility in beam shaping.
Why dielectric function as optical properties is an important parameter in dft calculation?5 answersThe dielectric function is an important parameter in density functional theory (DFT) calculations because it provides information about the optical properties of materials. It allows for the analysis of the electron band structure, grain structure, band gap, temperature, composition, phase structure, and carrier mobility of semiconductors. The dielectric function is used to study the structural, electronic, and optical properties of materials, such as absorption coefficient, conductivity, and refractive index. Different models of the dielectric function can affect the interpretation of experimental results and the calculation of various quantities, such as the electron inelastic mean free path and proton stopping and straggling. The dielectric function can be measured experimentally using techniques like reflection electron energy-loss spectroscopy (REELS) and compared to DFT calculations, providing valuable insights into the electromagnetic response of surfaces. Additionally, the dielectric function is used in the calculation of excitonic optical properties in 2D semiconductors, taking into account non-local effects and substrate screening.
Who were the most important contributors to the formulation of electromagnetic theory?5 answersThe most important contributors to the formulation of electromagnetic theory were Michael Faraday and James Clerk Maxwell. Faraday, an experimentalist, made significant discoveries regarding the nature of electromagnetism, providing a foundation for Maxwell's work. Maxwell, using his mathematical skill, unified the science of electromagnetism into a coherent theory, complete with mathematical formalism. His seminal paper explained the nature of electromagnetic potential and its connection to the propagation of light, setting the stage for Einstein's discovery of special relativity. Grassmann also made contributions to electromagnetics with his mathematical ideas, including his exterior algebra leading to differential forms, force law, and law of optics. While Hendrik Antoon Lorentz and Ludvig Valentin Lorenz made important contributions, they are sometimes confused, with the more famous Lorentz often credited with the contributions of the less celebrated Lorenz.
What are the properties of the radial wave function?5 answersThe properties of the radial wave function include its dependence on the metric and its similarity to the Minkowskian case. The radial wave functions satisfy second order nonhomogeneous differential equations with three nonhomogeneous terms that depend on time and space curvatures. These terms vanish locally, reducing the radial equations to the same homogeneous equations as in Minkowski spacetime, in accordance with the principle of equivalence. The radial wave equation in Schwarzschild's space-time has solutions related to irregular singular points at x=+∞, and their analytic continuations are derived. Explicit expressions for solutions about the regular singular point at x=xs are also given. The non-compact group O (2, 1) is used to investigate hydrogenic radial wavefunctions, which are shown to form bases for infinite dimensional representations of the algebra of O (2, I). The Wigner-Eckart theorem is valid for this group, and the Clebsch-Gordan coefficients are proportional to the R(3) Clebsch-Gordan coefficients. The properties of radial wave functions relevant to the partial wave analysis of scattering theory are analyzed, including regular and irregular solutions, Jost function, S matrix, and Green's functions.
