DOI: 10.1109/tmtt.2023.3311992
Abstract: A method-of-moments (MoMs) approach is proposed for the modal analysis of two-dimensional (2-D) all-metal leaky-wave structures periodic along one direction. The electric-field integral equations (EFIEs) for both TM and TE polarizations are formulated in the… read more here.
