TL;DR: In this paper, a medical device-powering wireless receiver for use with a first electromagnetic resonator coupled to a power supply is presented, which includes a load configured to power an implantable medical device using electrical power, and a second EM resonator adapted to be housed within the medical device and configured to be coupled to the load.
Abstract: A medical device-powering wireless receiver for use with a first electromagnetic resonator coupled to a power supply. The wireless receiver includes a load configured to power an implantable medical device using electrical power, and a second electromagnetic resonator adapted to be housed within the medical device and configured to be coupled to the load, wherein the second electromagnetic resonator is configured to be wirelessly coupled to the first electromagnetic resonator to provide resonant, non-radiative wireless power to the second electromagnetic resonator from the first electromagnetic resonator, the area circumscribed by the inductive element of at least one of the electromagnetic resonators can be varied to improve performance.

08 Mar 2001TL;DR: In this article, an array of dielectric resonator antenna elements (e.g., a DAS) is composed of a single DAS disposed on a grounded substrate and a plurality of feeds for transferring energy into and from the DAS, where the feeds of each element are activatable either individually or in combination.
Abstract: An array of dielectric resonator antenna elements (1), each element (1) being composed of a dielectric resonator disposed on a grounded substrate (3), a plurality of feeds (2) for transferring energy into and from the dielectric resonator elements (1), wherein the feeds (2) of each element (1) are activatable either individually or in combination so as to produce at least one incrementally or continuously steerable beam which may be steered through a predetermined angle. Both the element beam patterns generated by the individual elements (1) and the array factor generated by the array as a whole may be independently steered. When these are steered in synchronism, it is possible to improve the overall gain of the array in any particular direction.

TL;DR: In this paper, a dielectric resonator antenna system is described, where a high-dielectric constant material is placed between a DRA and the antenna feed to enhance the coupling.
Abstract: A dielectric resonator antenna system is disclosed wherein a dielectric material having a high dielectric constant is placed between a dielectric resonator antenna (DRA) and the antenna feed. Preferably the dielectric material having a high dielectric constant is either in the form of an insert within a cavity of the DRA or alternatively is in the form of a thin layer between the feed and the DRA for enhancing coupling therebetween. It is preferred that the high dielectric constant material be at least twice the value of the dielectric resonator antenna.
