Review on Photoconductive Antenna Design from Conventional to Microstructures
Abstract: Semiconductors possess many diverse phenomena under terahertz-frequency electromagnetic radiation (THz). This is due to the fact that the energy of THz photons is at quite large scales in case of bulk and low-dimensional materials and devices. With regard to broadband THz sources, various inorganic crystals such as ZnTe/GaP/GaAs/GaSe/DAST/LiNbO3 have been used which are pumped by femtosecond laser pulses. These pulses are combined with field-resolved detection through electro-optic sampling using similar …

Simulation of Electric Field Induced by Electromagnetic Radiation on Spherical Nanoparticles
Abstract: AbstractIn this article, the interaction of light and matter of nanoparticles is simulated for the electric field induced by electromagnetic radiation on spherical nanoparticles. The absorption, scattering and extinction efficiencies are demonstrated for initial wavelength of the incident of light from 300 nm to the final wavelength at 900 nm range for the silver material of 250 nm (spherical nanoparticles) radius with 1.0 refractive index. These optical properties vary according …
