摘要
Closed-form expressions for the effective electromagnetic material properties of honeycomb composites and electromagnetic absorbers constructed in the shapes of alternating wedges and hollow pyramids are presented. These expressions can be used to efficiently calculate the interaction of electromagnetic fields with periodic structures of said geometries. The effective material properties from these expressions are compared to results obtained from a numerical solution of the actual cross-sectional geometry. Finally, we give guidance on how the expressions presented here and elsewhere can be used for other types of periodic geometries.
