On the numerical simulation of metasurfaces with impedance boundary condition integral equations
IEEE Transactions on Antennas and Propagation, 2015•ieeexplore.ieee.org
Metasurfaces are thin metamaterial layers characterized by unusual dispersion properties of
surface/guided wave and/or reflection properties of otherwise incident plane waves. At the
scales intervening in their design, metasurfaces can be described through a surface
impedance boundary condition. The impedance, possibly tensorial, is often “modulated,” ie,
it can vary from place to place on the surface (by design). We investigate on different integral
equation formulations of the problem, with special attention to the stability properties of the …
