In this article, the unidirectional current screen was used as an asymptotic strip boundary condition (ASBC) for analysis of field problems containing metal strip grids.Abstract:
We discuss the unidirectional current screen as an asymptotic strip boundary condition (ASBC) for analysis of field problems containing metal strip grids, and we introduce a related asymptotic corrugation boundary condition (ACBC) for analysis of corrugated surfaces. The boundary conditions are asymptotic in the sense that the exact boundary conditions approach the asymptotic ones when the strip and corrugation periods approach zero. © 1997 John Wiley & Sons, Inc.

Three metamaterial-based gap waveguides between parallel metal plates for mm/submm waves
TL;DR: In this article, the basic ideas of how local waveguides and transmission lines can be designed to propagate along desired paths in the air gap between two metal surfaces are presented, related to the performance of artificial magnetic conductors, EBG surfaces and soft and hard surfaces.

Electromagnetic scattering from BOR objects loaded with periodic conducting narrow strips using asymptotic boundary conditions
TL;DR: In this article, the ASBC method is verified by using it to obtain the scattering fields from objects and comparing them with those obtained using the exact boundary conditions, where the strips are tangential to the surface and either in the circumferential direction or orthogonal to it.

TL;DR: This paper will describe the personal experiences with what today is referred to as metamaterials, and in particular in my case metasurfaces, and the concept of soft and hard surfaces, which has since 2009 developed into a novel gap waveguide technology.
