Title: The Innovative Contributions of Norman Apsley
Introduction
Norman Apsley is a notable inventor based in Malvern, GB. He has made significant contributions to the field of electro-optical devices and antenna technology. With a total of 2 patents to his name, Apsley's work showcases his expertise and innovative spirit.
Latest Patents
Apsley's latest patents include an electro-optical device and an antenna device. The electro-optical device is designed as a Fabry Perot etalon, which consists of two mirrors and a central region. The mirrors are multilayer heterostructures made from Al.sub.x Ga.sub.1-x As semiconductor materials, where the value of x alternates between 1.0 and 0.3. The central region may feature a multiple quantum well structure of Al.sub.x Ga.sub.1-x As, with x varying between 0 and 0.3. This innovative design allows for a non-uniform doping of the etalon material, making it an electrically biasable semiconductor device. The optical path length in the central region is dependent on the electric field, enabling modulation of the etalon's transmission or reflection by varying the central region bias.
The antenna device comprises a dielectric sheet substrate with an antenna patch on one surface and a ground plane on the opposite side. A hemispherical dielectric lens is positioned over the antenna patch, enhancing the efficiency of radiation coupling. This design minimizes power trapping in the substrate, a common issue in prior art microstrip patch antennas. The antenna device is capable of radiating into a narrow cone perpendicular to the antenna patch, theoretically achieving 100% coupling of radiation from a power source to free space.
