%X A simulation model has been developed to calculate the transmission and absorption of electromagnetic waves by inhomogeneous spherically symmetric plasma.In this model,the nonuniform sphere is modeled by numbers of concentric spherical shells,and each has a fixed electron density.Using the geometrical optics approximation and considering that the phase coefficient and attenuation coefficient are vectors,we have studied the property of absorption and transmission of electromagnetic waves by inhomogeneous spherically symmetric plasma for different collision frequency,central plasma density and frequency of electromagnetic waves for three typical density distribution profiles.Some useful results are obtained.
