| Abstract: | This paper studies the radiation of transient electromagnetic fields at a waveguide end by using difference maxwell' equations in a time domain, and presents the different directivity patterns of electromagnetic powers with different wave envelopes. The reflection of the fields due to the discontinuity at the waveguide end have been investigated. It compares the results in a transient state with those in a steady state, points out the limitation of the numerical method, and conducts a theoretical analysis of the numerical results. |
