In this paper, polarisation scattering matrices are used to investigate the possibility of developing variable differential phase sections (DPS) made of birefringent elements based on the form birefringence effect. The possibility of developing quarter-wave and half-wave differential phase sections variable in a wide frequency range has been shown. Analysis has confirmed the possibility of developing...
Energy spectra, electron mobilities, resistances and noises in the semi-metallic n-type Hg0.32Cd0.68Te/Hg1−xCdxTe quantum well at T = 77 K are numerically modeled in this work. The modeling is provided on the basis of direct iterative solution of Boltzmann transport equation and accounts bands mixing, non-parabolicity of dispersion law, proper screening in 2DEG and inelasticity of electron scattering...
Antennas are a key element in the wireless communication world of today, however, the significant disadvantage of microstrip antennas is its low bandwidth. In this work a microstrip planar antenna with enhanced bandwidth has been discussed. This antenna can be treated as an Ultra Wide Band (UWB) microstrip antenna due to the obtained frequency range of 12.9 GHz. The enhancement derives mainly from...
A new method for solving scattering from a cylinder partially buried in a material half space for TMz polarization is presented with example scenarios. The surface equivalence principle is used with the decomposition method in order to calculate the current densities in the calculation domain. The Method of Moments (MoM) is used to solve the electric field integral equations (EFIE) in the frequency...
