Abstract :
The current excited by a delta-gap source on a periodically loaded microstrip line is studied by means of the array scanning method. The method requires the efficient solution of a large number of auxiliary Floquet-periodic subproblems, cast here in the form of an electric-field integral equation (EFIE) that has been discretized with the method of moments (MoM) in the unit cell. Numerical results are provided for a specific structure in both bound and radiative frequency ranges and are validated through independent codes.
