Toroidal metamaterial
K. Marinov, A. D. Boardman, V. A. Fedotov +1
It is shown that a new type of metamaterial, a 3D-array of toroidal solenoids, displays a significant toroidal response that can be readily measured. This is in sharp contrast to m…
Radiation enhancement and radiation suppression by a left-handed metamaterial
A. D. Boardman, K. Marinov
The perfect lens property of a dispersive and lossy left-handed metamaterial (LHM) disk is exploited to superimpose a source of electromagnetic radiation onto its mirror image, for…
Electromagnetic energy in a dispersive metamaterial
A. D. Boardman, K. Marinov
An expression for the electromagnetic field energy density in a dispersive, lossy, left-handed metamaterial, consisting of an array of split-ring resonators and an array of wires i…
Non-radiating and radiating configurations driven by left-handed metamaterials
A. D. Boardman, K. Marinov
It is shown that a pair of identical emitters (e.g. wire dipole antennas) in the focal points of a disc, made of left-handed metamaterial (a "perfect" lens), form a non-radiating e…
Nonradiating toroidal structures
A. D. Boardman, K. Marinov, N. Zheludev +1
Some basic properties of nonradiating systems are considered. A simple connection is established between the existence of residual electromagnetic potentials and the current densit…
Dispersion properties of non-radiating configurations: Finite-Difference Time-Domain modeling
A. D. Boardman, K. Marinov, N. Zheludev +1
A finite-difference time-domain (FDTD) numerical analysis is used to demonstrate that a toroidal solenoid, coaxial with an electric dipole, is a remarkable non-radiating configurat…
