Abstract
A Method of Moments (MoM) based analysis is presented for elliptical aperture metasurface (MTS) antennas. The MTS is represented as a sheet transition impedance boundary condition incorporated in a transmission line which accounts for the substrate interaction with the patches layer. The algorithm uses the Fourier-Bessel basis functions (FBBFs) and is inspired from the circular domain analysis. The computation time is then comparable to that of an equivalent size circular aperture MTS. Numerical results obtained with the proposed method are compared with the full wave Contour-FFT (CFFT) based MoM simulation of a MTS implemented with sub-wavelength printed patches.
