The objective was to find for radome design engineers an electrical approach which would permit more adequate environmental design for the microwave and especially the millimeter regions. To escape the structural dependence upon the thickness requirement of the customary phase delay design, phase advance possibilities were examined. This led to a study of the perforation of a structural metal plate for phase advance properties and sandwiching it between protective dielectric phase delay layers. The characteristics of an inductive two-dimensional lattice of very small circular holes were studied and selected as the most promising. It was concluded that while improved environmental adequacy would be inherent, workable design techniques could not be made ready until susceptance theory for holes in lattices was amplified, put in engineering form and test data reconciled with it.
