%X A method of signal extraction in time domain is proposed in this paper, by means of which, the time-domain incident wave and reflected wave on the reference plane of the feeder can be extracted from the total-field responses obtained from the time-domain simulation for the microwave components fed by the nondispersive transmission lines, furthermore, its frequency-domain parameters can also be acquired. By comparison with traditional methods, it can avoid to directly compute the time-domain incident wave and reflected wave using the finite-difference time-domain method, so computation time and storage can be reduced. The numerical simulations of rectangular microstrip antenna show that the computation precision of this method is the same as that of traditional methods.
