Ps. Kildal et al., ASYMPTOTIC BOUNDARY-CONDITIONS FOR STRIP-LOADED AND CORRUGATED SURFACES, Microwave and optical technology letters, 14(2), 1997, pp. 99-101
We discuss the unidirectional current screen as an asymptotic strip bo
undary condition (ASBC) for analysis of field problems containing meta
l strip grids, and we introduce a related asymptotic corrugation bound
ary condition (ACBC) for analysis of corrugated surfaces. The boundary
conditions ale asymptotic in the sense that the exact boundary condit
ions approach the asymptotic ones when the strip and corrugation perio
ds approach zero. (C) 1997 John Wiley & Sons, Inc.
