The radiation and frequency characteristics, together with the sum and difference performance of the wave front matching (WFM) lens antenna and the shaped lens (SL) antenna are studied in this paper. The performances of these antennas are analyzed using finite element method. The Radiation pattern of these two antennas are computed and given, which show that both the antennas have low side lobe level...
The theory is presented for one method of determining the biological thermal effect of millimeter waves in microwave radiometry. It has been studied theoretically that millimeter waves propagation and absorption in a human body. The model is a plane straticulate homogeneous slab of tissues under the irradiance of normal incidence plane wave. It has been discussed by obtaining the electromagnetic field,...
