The present invention is directed to a composite material with a high dielectric constant. In certain embodiments, the composite material of the invention is biocompatible and is used in an implantable medical device, such as an implantable antenna, probe, sensor or electrode. In certain embodiments, the present invention comprises a biocompatible conductive or semi-conductive filler comprising filler particles dispersed within a biocompatible electrically insulating material. The filler particles may comprise an electrically insulating coating.

Composite material with high dielectric constant and use in biocompatible devices

An electro-optically triggered power switch is disclosed utilizing a wide bandgap, high purity III-nitride semiconductor material such as BN, AlN, GaN, InN and their compounds. The device is electro-optically triggered using a laser diode operating at a wavelength of 10 to 50 nanometers off the material's bandgap, and at a power level of 10 to 100 times less than that required in a conventionally triggered device. The disclosed device may be configured as a high power RF MOSFET, IGBT, FET, or HEMT that can be electro-optically controlled using photons rather than an electrical signal. Electro-optic control lowers the power losses in the semiconductor device, decreases the turn-on time, and simplifies the drive signal requirements. It also allows the power devices to be operated from the millisecond to the sub-picosecond timeframe, thus allowing the power device to be operated at RF frequencies (i.e., kilohertz to terahertz range) and at high temperatures where the bandgap changes with temperature.

Optically controlled power devices

Systems and methods for the controlled delivery of laser light to target tissue using an improved waveguide. A waveguide controls transmission of wave energy to a target based on direct contact with the target. The waveguide comprises a propagation medium, a cladding causing the electromagnetic wave to be internally reflected in the medium, and an interface formed in the cladding and configured for direct contact with the target. A portion of the laser light penetrates through the cladding at the interface and propagates into the target while a portion internally reflects within the propagation medium.

The presence of a non-linear electronic component of the IED can be detected by illuminating the device with a high power microwave signal containing a plurality of radio frequencies of electromagnetic radiation and receiving sum and/or difference frequency components that are produced by interaction of the illuminating signals with a non-linear IED component and subsequently re-radiated.

Method and apparatus for switching high power at high repetition rates. The apparatus is preferably a switch utilizing a pressurized flowing dielectric. The pressurized dielectric suppresses growth of dielectric breakdown byproducts, such as large bubbles and breakdown contamination, enabling lower dielectric flow rates to remove the byproducts. In addition to the advantage of lower flow rates, and thus smaller and lighter pumping means, the switch can switch high energies (up to megajoules) at fast repetition rates, up to thousands of pulses per second. The switch is preferably triggered to reduce jitter. The switch can also be used to remove water from oil.
