Additional Boundary Condition for a Wire Medium Connected to a Metallic Surface
Mario G. Silveirinha, Carlos A. Fernandes, Jorge R. Costa
In this work, we demonstrate that the interaction of electromagnetic waves with a microstructured material formed by metallic wires connected to a metallic surface can be described…
Theory of Supercoupling, Squeezing Wave Energy, and Field Confinement in Narrow Channels and Tight Bends Using Epsilon-Near-Zero Metamaterials
Mario Silveirinha, Nader Engheta
In this work, we investigate the detailed theory of the supercoupling, anomalous tunneling effect, and field confinement originally identified in [M. Silveirinha, N. Engheta, Phys.…
Nanoinsulators and nanoconnectors for optical nanocircuits
Mario G. Silveirinha, Andrea Alu, Jingjing Li +1
Following our recent idea of using plasmonic and non-plasmonic nanoparticles as nanoinductors and nanocapacitors in the infrared and optical domains [N. Engheta, A. Salandrino, and…
Design of Linear-to-Circular Polarization Transformers Made of Long Densely Packed Metallic Helices
Mario G. Silveirinha
In this work, we study the realization of realistic polarization transformers formed by long metallic helices. To this end, we propose a new homogenization model to characterize th…
