Abstract :
The finite difference in time domain method was used to study the wave propagation in a microstrip line. The boundary condition implemented at the excitation source plane causes an amplification effect on the resulting field at the source plane. The amplification factor depends on the time, spatial intervals and the effective dielectric constant of the microstrip line. The numerical origin of this effect is investigated.
