Optimization of Iterative Algorithms for Focusing Light Through Scattering Media by Yulan Zhou, Xun Li

“…Two independent processes, characterizing the transmission matrix (TM) of the scattering media and calculating the phase compensation of the SPM, are included in our optimized algorithm. While the TM of the scattering media is determined through the interference effect and the light reciprocity principle, the phase compensation of the SPM is calculated using the Rayleigh–Sommerfeld diffraction theory. …”

Flat Dielectric Waveguides of the Terahertz Range and Diffraction Antennas on Their Basis by I. G. Mironenko, S. S. Sokolov, A. A. Ivanov

“…In this work, we use the principles of the finite element method to solve the problem of finding a propagation constant in a flat multilayer dielectric waveguide, and show how to reduce the number of elements when setting optimal boundary conditions. Based on the obtained computational model, the possibility of constructing diffraction antennas operating in the THz range is considered.Aim. …”
