Abstract
Surface impedance boundary conditions (SIBC) for lossy metal layers are presented that are not limited to the frequency range in which a metal layer is thicker than several skin depth. A metal layer is considered as a TEM transmission line so that the SIBCs can be obtained as the input impedances of an open ended and a short circuited transmission line, respectively. The SIBCs are verified for a MMIC microstrip line and a coplanar waveguide.
