Self-amplified Emission of Cherenkov Radiation from a Relativistic Particle Inside Layered Dielectric-filled Waveguide [PDF]

open access: yes, 2010
It is shown that in some special cases the Cherenkov radiation from a charged particle moving along the axis of cylindrical waveguide filled with a semi-infinite material consisting of dielectric plates alternated with vacuum gaps is many times stronger ...

Guiding mechanisms in dielectric-core photonic-crystal optical waveguides [PDF]

open access: yes, 2001
We show that the main guiding mechanisms in dielectric-core photonic crystal optical waveguides are total internal reflection and distributed Bragg reflection.

Measurement of the Dielectric Constant and Loss Tangent of Thallium Mixed Halide Crystals KRS-5 and KRS-6 at 95 GHz [PDF]

open access: yes, 1981
The dielectric constants and loss tangents of KRS-5 and KRS-6 thallium halide mixed crystals have been measured at 95 GHz using both the shorted waveguide (SWG) reflection method and the Fabry-Perot (F-P) transmission method on samples filling standard ...

Square dielectric THz waveguides

open access: yesOptics Express, 2016
A holey cladding dielectric waveguide with square cross section is designed, simulated, fabricated and characterized. The TOPAS waveguide is designed to be single mode across the broad frequency range of 180 GHz to 360 GHz as shown by finite-difference time domain simulation and to robustly support simultaneous TE and TM mode propagation.

Efficient Coupling Between Photonic and Dielectric-Loaded Surface Plasmon Polariton Waveguides With the Same Core Material

open access: yesIEEE Photonics Journal, 2014
We theoretically investigate how to efficiently couple a photonic waveguide to a dielectric-loaded surface plasmon polariton (DLSPP) waveguide when they are based on a common core material.

Mode-matching analysis of a shielded rectangular dielectric-rod waveguide [PDF]

open access: yes, 2005
Rectangular cross-section dielectric waveguides are widely used at millimeter wavelengths. In addition, shielded dielectric resonators having a square cross-section are often used as filter elements, however there is almost no information available on ...
