Superlens made of a metamaterial with extreme effective parameters
M. G. Silveirinha, C. A. Fernandes, J. R. Costa
We propose a superlens formed by an ultra-dense array of crossed metallic wires. It is demonstrated that due to the anomalous interaction between crossed wires, the structured subs…
Transmission-Line Analysis of Epsilon-Near-Zero (ENZ)-Filled Narrow Channels
Andrea Alu, Mario G. Silveirinha, Nader Engheta
Following our recent interest in metamaterial-based devices supporting resonant tunneling, energy squeezing and supercoupling through narrow waveguide channels and bends, here we a…
Reflectionless Sharp Bends and Corners in Waveguides Using Epsilon-Near-Zero Effects
Brian Edwards, Andrea Alu, Mario G. Silveirinha +1
Following our recent theoretical and experimental results that show how zero-permittivity metamaterials may provide anomalous tunneling and energy squeezing through ultranarrow wav…
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…
