Journal ArticleDOI
Using a discrete dipole approximation to predict complete scattering of complicated metamaterials
TL;DR: In this article, the authors developed a numerical technique for simulating metamaterial electromagnetic response based on an adaptation of the discrete dipole approximation (DDA), which reduces each constituent of a composite to a point dipole with electric and magnetic polarizabilities.
Journal ArticleDOI
Reply to Comments on "Resonant and antiresonant frequency dependence of the effective parameters of metamaterials"
TL;DR: In this paper, the authors argue that periodicity of the metamaterial is responsible for antiresonant behavior of the effective permittivity as well as for the negative sign of the imaginary part of an effective permitivity or permeability.
Journal ArticleDOI
A $Ku$ -Band High- $Q$ Tunable Filter With Stable Tuning Response
TL;DR: In this article, a Ku-band tunable filter with a very stable notch level and in-band RF performance is presented, which employs two dual-mode TE113 tunable cavity resonators with a set of flexible bellows.
Journal ArticleDOI
Efficient complementary metamaterial element for waveguide-fed metasurface antennas.
TL;DR: The metamaterial element is an electrically-small, complimentary electric-LC (cELC) resonator designed to exhibit large radiated power while maintaining low ohmic losses in a waveguide-fed metasurface antennas.
Journal ArticleDOI
Coupled-mode theory for film-coupled plasmonic nanocubes
Patrick T. Bowen,David R. Smith +1 more
TL;DR: In this article, an expanded analytical analysis of the plasmonic patch geometry, applying an eigenmode expansion method to arrive at a more accurate description of the field distribution underneath a film-coupled planar nanocube, is presented.
