How metabarriers work in hsts wave mitigation?
Best insight from top research papers
Metabarriers work in seismic wave mitigation by attenuating the impact of the waves on structures. They are designed as arrays of sub-wavelength resonators embedded in a granular medium. When seismic waves collide with the metabarriers, the wavefront is back-scattered and steered downward underneath the oscillators. Part of the wavefield is then rerouted to the surface level after overcoming the resonant array. The insertion of additional layers of resonators leads to greater and broader band wave attenuation compared to a single layer case . Metabarriers can also be used to shield structures from incoming seismic waves. They can reduce the spectral amplification of the superstructure by approximately 15-70% depending on various parameters such as the size of the metastructure and the properties of the soil . The effectiveness of metabarriers in wave mitigation has been validated through numerical simulations and analytical solutions .

How metabarriers work in High speed Train wave mitigation?5 answersMetabarriers are structures designed to mitigate the impact of waves, such as vibrations or seismic waves, in high-speed train environments. These barriers are composed of arrays of sub-wavelength resonators that are embedded in the ground or placed along the train tracks. The resonators in the metabarriers interact with the incoming waves, causing back-scattering and redirection of the wavefront. This interaction leads to the attenuation of the waves, reducing their impact on the surrounding environment. The effectiveness of metabarriers in wave mitigation depends on factors such as the depth and number of layers of resonators, as well as the properties of the surrounding medium. Studies have shown that multi-layer arrangements of resonators result in greater and broader band wave attenuation compared to single-layer cases. The use of metabarriers can provide significant reduction in vibrations and noise caused by high-speed trains, benefiting nearby residents, sensitive equipment, and high-tech production facilities.
How can toroidal dipole metasurfaces be used to control the flow of electromagnetic waves?5 answersToroidal dipole metasurfaces can be used to control the flow of electromagnetic waves by exploiting their unique properties. A deep learning algorithm can be used to simulate the relationship between the structural parameters of the metasurfaces and their scattered powers, allowing for quick prediction of the scattered powers based on input parameters. All-dielectric metasurfaces composed of high-permittivity ceramic cuboid resonators embedded in polylactic acid have been investigated as angular-dependent polarization beam splitters. These metasurfaces operate based on strong toroidal resonances with highly asymmetric Fano profiles, allowing for large extinction ratios, low insertion losses, and mechanically tunable polarization beam splitting ratios. Additionally, toroidal dipole moments have been shown to play a dominant role in exciting sharp Fano resonances in all-dielectric metasurfaces consisting of arrays of crosses, which can be used for sensing applications such as refractive index sensing.
Hoe trenches work on mitigating hst vibrations?3 answersTrenches are used to mitigate ground vibrations caused by high-speed trains (HSTs). The effectiveness of trenches in reducing vibrations depends on various factors. The frequency of vibrations has a greater influence on screening effectiveness than the depth of the trench. Trenches can be used as wave barriers to isolate vibrations, and their screening effectiveness is affected by the type of vibration source and the geometric dimensions of the trench. In the case of railway traffic, the efficiency of absorbing barriers, such as trenches, has been evaluated through field experiments. Dual or two trenches can be used to mitigate ground vibrations, and their effectiveness can be evaluated using artificial neural networks. Meta-trenches, which are composed of an array of resonant units buried in the ground, can also be used to reduce ground motion caused by railways and subways.
What are the different NLOS mitigation algorithms?5 answersNLOS mitigation algorithms include strategies for transforming NLOS channels into equivalent LOS channels, NLOS identification methods, and algorithms based on time of arrival (TOA) measurements. Carpi et al. propose a strategy where NLOS channels are pre-mitigated and transformed into LOS channels to improve distance estimation. Zhou et al. perform NLOS identification based on position difference, received signal strength, and distance residuals, and propose an NLOS error mitigation method using biased Kalman filtering and maximum likelihood estimation. Zhang et al. propose a TOA NLOS mitigation algorithm based on topological units, which successfully identifies adjacent NLOS measurements and re-estimates them using topological units. Wang et al. use a deep generative model to mitigate NLOS bias errors in ultra-wide bandwidth systems, improving localization accuracy. Dong et al. develop a robust estimator based on maximum likelihood and use Lagrange programming neural network to mitigate NLOS bias errors in TOA-based localization.
Metamaterial for radar cross section reduction?5 answersMetamaterials have been widely studied for radar cross section (RCS) reduction. Different methods have been explored to achieve RCS reduction, including the use of metamaterial structures. By loading metamaterial structures onto an antenna, the electromagnetic characteristics of the antenna can be manipulated, resulting in a reduced RCS. Various types of metamaterial antennas have been investigated for RCS reduction, such as L-structured and Square-structured fractal metamaterial antennas. Additionally, metasurfaces with diffusive parabolic phase distributions have been designed to achieve wide-angle low scattering and wideband RCS reduction. Another approach involves using a digital coding metasurface controlled by optical light to dynamically manipulate the electromagnetic wave and reduce RCS. These advancements in metamaterial design offer promising applications in stealth and military technology.
How can we design metasurfaces that generate wideband OAM vortex beams?3 answersMetasurfaces that generate wideband OAM vortex beams can be designed using various approaches. One approach is to use active metasurfaces in reflection manner, which can generate reconfigurable OAM vortex beams with high purity in a specific frequency range. Another approach is to design flat Pancharatnam-Berry (PB) metasurfaces with low RCS, which can generate scattered vortex waves with orbital angular momentum (OAM). Additionally, all-dielectric geometric metasurfaces can be used to generate perfect vortex beams (PVBs) with specific topological charges (TCs) based on tailored spiral phase distributions. Furthermore, an all-graphene geometric metasurface operating in the terahertz (THz) band can generate multidimensional vortices by introducing the superposition of two helical phases with the same topological charge within orthogonal circularly polarized (CP) channels. These design approaches provide different methods for generating wideband OAM vortex beams with various applications in optical communication and manipulation.
