Perfectly conducting metals may be structured with holes to make metamaterials that support surface-plasmon-like modes at microwave frequencies. Results are presented for Fabry-Pérot-like standing wave resonances formed from coupled surface-plasmon-like modes supported by two such perforated metal substrates placed in close proximity.
