Abstract: In this paper we present a fast time-domain algorithm to
study the electromagnetic pulse heating on dispersive medium. Using the
proposed fast algorithm, the long heating process can be compressed by
accelerating thermal conduction and scaling the power dissipation density.
Comparing with the previous computation of several pulse periods, the
proposed algorithm can deal with the heating process up to billions of pulse
periods. Besides, employing the proposed algorithm, we study a 2D water post
heated by electromagnetic pulses. The results reveal that comparing with
continuous microwave heating, pulse heating cannot improve temperature
uniformity or enhance heating efficiency.
Keywords: Electromagnetic pulse heating, fast algorithm, temperature uniformity, heating efficiency, Debye medium
