abstract = {<p style="text-align: justify;">Computational simulation of the radiating structure of a microwave from
a pyramidal horn has been successfully accomplished. This simulation capability is developed for plasma diagnostics based on a combination of three-dimensional Maxwell
equations in the time domain and the generalized Ohm&#39;s law. The transverse electrical
electromagnetic wave of the TE<sub>1,0</sub> mode propagating through a plasma medium and
transmitting from antenna is simulated by solving these governing equations. Numerical
results were obtained for a range of plasma transport properties including electrical conductivity, permittivity, and plasma frequency. As a guided microwave passing through
plasma of finite thickness, the reflections at the media interfaces exhibit substantial
distortion of the electromagnetic field within the thin sheet. In radiating simulation,
the edge diffraction at the antenna aperture is consistently captured by numerical solutions and reveals significant perturbation to the emitting microwave. The numerical
solution reaffirms the observation that the depth of the plasma is a critical parameter
for diagnostics measurement.</p>},
