Interaction of thin conductive sheets with TE10 electromagnetic wave in rectangular waveguide

Numerical investigation of a thin conductive layer, interacting with TE
₁₀
electromagnetic field mode in rectangular waveguide, was performed. A finite-difference time-domain method with subcell technique was applied to perform the modelling. The distribution of the electric field in the layer and the reflection coefficient from it have been calculated for different length, shape and conductivity structures. These investigations can be useful for the development of high frequency microwave sensors, the operation of which is based on a non-uniform carrier heating effect in the layer.
