Abstract
Impedance Boundary Condition (IBC) is a widely used approximation in the analysis of metasurfaces, and it greatly simplifies the design process. However, for some ranges of impedance values of practical interest in metasurface applications, the Integral Equation formulation has shown instabilities. This contribution proposes a way to improve that shortcoming; the method is based on the property of the involved operators and the nature of the IBC approximation.
