Substrate size selection of microstrip‐fed cylindrical dielectric resonator antennas for lowering the cross‐polarisation

IET Microwaves, Antennas & Propagation, 2019
A cylindrical dielectric resonator antenna (DRA) has been excited with a microstrip line in the HEM 11δ mode. It is demonstrated that at the operating frequency, minimum cross-polarisation occurs when the lateral dimension of the substrate is slightly ...

The dielectric constant of a lattice of polarisable spheres [PDF]

open access: possibleJournal of Physics A: Mathematical and General, 1980
The response of a simple cubic lattice of spacing L with a polarisable sphere of polarisability alpha at each vertex to a permanent dipole mu at one vertex deep within the lattice is evaluated.

Polarisation-independent blue-phase liquid crystal microlens array with different dielectric layer

Liquid crystals (Print), 2018
A fast response (sub-milliseconds) and polarisation-independent blue-phase liquid crystal (BPLC) microlens array with periodical double layer electrodes using different dielectric layers is proposed.

A variable polarisation compensator using artificial dielectrics

Optics Communications, 1999
Abstract Artificial dielectrics can be made to exhibit strong birefringence. This property may be used to construct waveplates for a variety of applications. In this article, a method for making a variable artificial dielectric retarder, akin to a Babinet–Soleil compensator, is investigated.

Fluctuations of partial polarisations in dielectrics

Journal of Physics C: Solid State Physics, 1979
A theory of fluctuations of partial polarisations in dielectrics is formulated on the basis of macroscopic phenomenological equations and thermodynamic fluctuation theory. The distinction between the high-frequency polarisability of molecules and the low-frequency dielectric behaviour of their permanent dipoles gives rise to the selection of local and ...

Dielectric Relaxation Study from Polarisability Data

Physics and Chemistry of Liquids, 1989
Abstract An analysis of the dielectric data using the polarisability plots have been carried out in our earlier paper [Current Sci. India 15 (1982) 695]. The polarisability equations proposed in our earlier paper have been modified by introducing a correction term.
