Parallel, Series, and Intermediate Interconnections of Optical Nanocircuit Elements Part 2: Nanocircuit and Physical Interpretation
Andrea Alu, Alessandro Salandrino, Nader Engheta
Applying the analytical closed-form solutions of the 'quasi-static' potential distribution around two conjoined resonant half-cylinders with different permittivities, reported in t…
Parallel, Series, and Intermediate Interconnections of Optical Nanocircuit Elements Part 1: Analytical Solution
Alessandro Salandrino, Andrea Alu, Nader Engheta
Following our recent development of the paradigm for extending the classic concepts of circuit elements to the infrared and optical frequencies [N. Engheta, A. Salandrino, A. Alu,…
Coupling of Optical Lumped Nanocircuit Elements and Effects of Substrates
Andrea Alu, Alessandro Salandrino, Nader Engheta
We present here a model for the coupling among small nanoparticles excited by an optical electric field in the framework of our optical lumped nanocircuit theory [N. Engheta, A. Sa…
Epsilon-Near-Zero (ENZ) Metamaterials and Electromagnetic Sources: Tailoring the Radiation Phase Pattern
Andrea Alu, Mario Silveirinha, Alessandro Salandrino +1
In this work, we investigate the response of epsilon-near-zero (ENZ) metamaterials and plasmonic materials to electromagnetic source excitation. The use of these media for tailorin…
Negative effective permeability and left-handed materials at optical frequencies
Andrea Alu, Alessandro Salandrino, Nader Engheta
We present here the design of nano-inclusions made of properly arranged collections of plasmonic metallic nano-particles that may exhibit a resonant magnetic dipole collective resp…
Circuit elements at optical frequencies: nano-inductors, nano-capacitors and nano-resistors
Nader Engheta, Alessandro Salandrino, Andrea Alu
We present some ideas for synthesizing nanocircuit elements in the optical domain using plasmonic and non-plasmonic nanoparticles. Three basic circuit elements, i.e., nano-inductor…
