A general review and comparison on two types widely adopted measurement techniques of dielectric constant and dielectric loss at microwave frequencies has been undertaken. Characteristics of various transmission/reflection techniques and resonance techniques are compared with each other. Suggestions on how to select adequate measurement techniques of microwave dielectric properties are given. T...
Effects of material and configuration of the internal wall on the performance of wideband channel are investigated by using the Finite Difference Time-Domain (FDTD) method. The indoor wideband channel characteristics, such as the path-loss, Root-Mean-Square (RMS) delay spread and number of the multipath components (MPCs), are presented. The simulated results demonstrate that the path-loss and M...
The presented work presents the results of studying temperature dependences dielectric constant and tangent loss angle biocomposites modified with fish scales. It was found that an increase in volumetric content bio-filler, increases, decreases. By varying it is possible to control properties desired direction.
