Abstract: A segmented stub has at least one serpentine signal path that increases the effective electrical length of the stub without increasing the overall physical length or area of the stub. This permits more compact monolithic millimeter-wave and microwave integrated circuit design.

Abstract: A multi layered high impedance structure presents a high impedance to multiple frequency signals, with a different frequency for each layer. Each layer comprises a dielectric substrate, and an array of radiating elements such as parallel conductive strips or conductive patches on the substrate's top surface, with a conductive layer on the bottom surface of the bottommost layer. The radiating elements of succeeding layers are vertically aligned with conductive vias extending through the substrates to connect the radiating elements to the ground plane. Each layer presents as a series of parallel resonant L-C circuits to an E field at a particular signal frequency, resulting in a high impedance surface at that frequency. The new structure can be used as the substrate for a microstrip patch antenna to provide an optimal electrical distance between the resonator and backplane at multiple frequencies.

Abstract: This heating cooling machine will use less power and will help stop heating fires and will be smaller compared to other heating/cooling machines.

Abstract: This invention will make life easier in the energy business. Plenty of clean heat or coolant. Heat it up past coolant level (since compression cools it) and it should be hot air at the end.

Abstract: An improved waveguide wall structure and improved waveguide using the new wall structure as the interior walls of the waveguide. The wall structure comprises a sheet of dielectric material, a series of parallel conductive strips on one side of the dielectric material and a layer of conductive material on the other side. Multiple conductive vias are also included through the dielectric material and between the conductive layer and conductive strips. The new wall structure presents as a series of parallel L-C circuits to a transverse E field at resonant frequency, resulting in a high impedance surface. The wall structure can be used in waveguides that transmit a signal in one polarization or signals that are cross polarized. The new waveguide maintains a near uniform density E field and H field component, resulting in near uniform signal power density across the waveguide cross section.
