In this paper a novel bio-inspired neural network (BINN) has been created for microwave diversity imaging compression. This work focuses on, firstly incorporating BINN and back propagation learning into a multiresolution, and secondly, training the highpass channel for perfect reconstruction so that the BINN filterbank within realistic coding conditions. Experiments have shown the robustness an...

The propagation of microwaves across a turbulent plasma density layer is investigated with fullwave simulations. To properly represent a fusion edge-plasma, drift-wave turbulence is considered based on the Hasegawa-Wakatani model. Scattering and broadening of a microwave beam whose amplitude distribution is of Gaussian shape is studied in detail as a function of certain turbulence properties. P...

Analyzing the production of weakly relativistic plasma produced by microwave fields with circular polarization the electron distribution function is obtained to be non-equilibrium and anisotropic. Furthermore, it is shown that produced plasma is accelerated on the direction of propagation of microwave electric fields. The electron velocity on this direction strongly depends on electron originat...

Microwave is an effective means to deliver energy to food through polymeric package materials, offering potential for developing short-time in-package sterilization and pasteurization processes. The complex physics related to microwave propagation and microwave heating require special attention to the design of process systems and development of thermal processes in compliance with regulatory r...

Failure to consider anomalous propagation of microwave radiation in the troposphere may result in erroneous meteorological radar measurements. The most commonly occurring anomalous propagation phenomenon over the ocean is the evaporation duct. The height of this duct is dependent on atmospheric variables and is a major input to microwave propagation prediction models. This evaporation duct heig...

To this end, the dispersive finite-difference time-domain method (FDTD) used with Convolutional Perfectly Matched Layered (CPML)...

Quantum limited amplifiers are sought after for a wide range of applications within quantum technologies and sensing. One promising candidate is the travelling wave parametric amplifier which exploits the non-linear kinetic inductance of a superconducting transmission line. This type of microwave amplifier promises to deliver a high gain, a quantum limited noise performance over several GHz ban...

In order to determine more accurate indicators of wood structure obtained by microwave sensing and improve our understanding of plane wave propagation through this complex material, we have undertaken a permittivity survey and experimentally investigated scattering of a plane wave, measuring its transmission over two non-parallel surfaces of a rectangular lumber sample. This novel non-destructi...
