Abstract :
The FDTD method is used for solving the electric field in the longitudinal resonant slot of a waveguide and radiant far field pattern, and according to equivalent circuit theory, the equivalent admittance is presented. The main characteristics of this method are summarized here, and some examples are given for demonstrating the advantages
