Dielectric-fibre surface waveguides for optical frequencies
A dielectric fibre with a refractive index higher than its surrounding region is a form of dielectric waveguide which represents a possible medium for the guided transmission of energy at opticalExpand

Dielectric-waveguide discontinuities
The discontinuity between two planar dielectric waveguides is examined on the basis of an integral-equation formulation. The aperture field is approximated by a finite set of discrete modes,Expand
Radiation from a solid-state laser
A correlation between the measured and theoretical radiation patterns of a solid-state laser gives additional confirmation of the laser parameters. It is shown that, by virtue of the laser geometry,Expand
Dual frequency multi-function radar antenna research
In 1995 the Radar Research Group within Sea Systems Sector at DERA Portsdown West began investigating dual frequency radar concepts under the Corporate Research Programme to overcome the currentExpand
Propagation in optical fiber waveguides
Investigation of a 90° corrugated horn
Wide-angle corrugated horns have found important practical applications as feeds for front-fed reflector antennas when low levels of crosspolarisation are required. A theoretical study has beenExpand
Use of the 'edge condition' in the numerical solution of waveguide-antenna problems
The application of moment methods to the solution of finite phased-array antennas using waveguide elements is well known. To reduce the matrix size use is made of the 'edge condition' to predict theExpand
