Investigations into Polarisations in Dielectric Resonator Antenna
2018This paper presented investigations into polarization for designing antennas. The left-hand and right-hand polarization switchable cylindrical DRA has been investigated using two crossed slots of unequal lengths. They couple energy through an aperture-coupled microstrip feed line.

Laser scribing of thin dielectrics with polarised ultrashort pulses
Optics and Lasers in Engineering, 2014Laser processing of thin glass has proven problematic due to the inefficient coupling of optical energy into glass and difficulty achieving economical processing speed while maintaining cut quality. Laser glass processing is pertinent to touch screen display, microfluidic, microoptic and photovoltaic applications.

Linear and circular polarised cylindrical dielectric resonator antennas
IEEE MTT/ED/AP/LEO Societies Joint Chapter. United Kingdom and Republic of Ireland Section. 1996 2nd High Frequency Postgraduate Student Colloquium, 2002A circular polarised and a switchable cylindrical dielectric resonator antenna are reported. The switchable antenna provides two linear polarised, one circular polarised, and a non-radiating mode. The experimental results of the resonant frequency, boresight axial ratio, gain, unloaded Q-factor, impedance bandwidth and radiation efficiency for both the

A strip loaded dielectric resonator antenna for circular polarisation
Microwave and Optical Technology Letters, 2006AbstractThe paper presents an experimental investigation of a cylindrical dielectric resonator antenna (DRA) with a conducting strip loaded on its top surface enabling circular polarisation. A simple 50Ω microstrip transmission line excites the antenna. The reflection, polarisation, and radiation characteristics of the antenna are studied.

Core polarisation in the dielectric response of simple metals
Solid State Communications, 1983Abstract The lowest core binding energy of a number of simple metals is close to the plasmon energy of the valence electrons. As a consequence the dielectric properties of these systems for ω of order of ωp are determined by the dynamics of both the valence- and the core electrons and by their mutual interaction.

Circular polarisation in ridge and dielectric loaded ridge waveguides
2000An important concept in microwave engineering is that of circular polarisation. The two possibilities correspond to two equal vectors in space quadrature with one or the other advanced or retarded in time quadrature. Counter-rotating magnetic fields occur naturally on either side of the symmetry plane of an ordinary rectangular waveguide propagating ...
