Abstract :
We study the reflection, transmission, and absorption of microwaves in nonuniform plasma. A discussion of the effect of various plasma parameters (such as electron density, collision frequency, etc.) on the reflected power, transmitted power and absorbed power of the microwave is presented. The nonuniform plasma slab studied is modeled by a series of subslabs, in each of which the electron density is assumed to be constant. We assume that the number density is constant in each subslab, and then the overall electron density is subject to a parabolic distribution. The total reflected, absorbed, and transmitted powers could then be deduced according to the calculation of the partial reflection coefficient and transmission coefficient at each slab.
