On the natural modes of helical structures
Sven Nordebo, Mats Gustafsson, Gerhard Kristensson +3
Natural modes of helical structures are treated by using the periodic dyadic Green's functions in cylindrical coordinates. The formulation leads to an infinite system of one-dimens…
Integral Equation Analysis of Plane Wave Scattering by Coplanar Graphene-Strip Gratings in the THz Range
Olga V. Shapoval, Juan Sebastian Gomez-Diaz, Julien Perruisseau-Carrier +2
The plane wave scattering and absorption by finite and infinite gratings of free-space standing infinitely long graphene strips are studied in the THz range. A novel numerical appr…
Sub-Wavelength Terahertz Spin-Flip Laser Based on a Magnetic Point-Contact Array
R. I. Shekhter, A. M. Kadigrobov, M. Jonson +3
We present a novel design for a single-mode, truly sub-wavelength THz disk laser based on a nano-composite gain medium comprising an array of metal/ferromagnetic point contacts emb…
Optical and modal features of hemielliptic dielectric lenses
A. V. Boriskin, R. Sauleau, A. I. Nosich
Any dielectric lens has a finite closed boundary and therefore is, in fact, an open dielectric resonator capable of supporting resonant modes whose Q-factor depends of the lens par…
Exact off-resonance near fields of small-size extended hemielliptic 2-D lenses illuminated by plane waves
A. V. Boriskin, R. Sauleau, A. I. Nosich
The near fields of small-size extended hemielliptic lenses made of rexolite and isotropic quartz and illuminated by E- and H-polarized plane waves are studied. Variations in the fo…
Performance of hemielliptic dielectric lens antennas with optimal edge illumination
A. V. Boriskin, R. Sauleau, A. I. Nosich
The role of edge illumination in the performance of compact-size dielectric lens antennas (DLAs) is studied in accurate manner using a highly efficient algorithm based on the combi…
