An apparatus includes a capsule configured to be launched or carried towards an unmanned aerial vehicle (UAV). The apparatus also includes a directed energy device within or carried by the capsule. The directed energy device includes a first inductor configured to generate an inductive magnetic field that is able to inductively couple into one or more electronics of the UAV in order to disable or destabilize the UAV. The capsule can be configured to be launched towards the UAV and can include a loiter mechanism (such as a rotor, umbrella, or parachute) configured to maintain a position of the capsule or to slow a descent of the capsule after launch. The capsule can also be configured to be carried towards the UAV by a different UAV, and the apparatus can further include a tether coupling the capsule to the different UAV.

An apparatus for conveying an electrical signal includes: a conductive pathway having a conductive material. The conductive material has a first edge and a second edge and is configured to convey the electrical signal. The apparatus also includes a resistive material in contact with at least a portion of the conductive pathway, covering an edge of the conductive pathway, and extending beyond the edge. The resistive material has a conductivity less than the conductivity of the conductive material.

A millimeter wave power source module may include N submodules, each of which includes M circuit devices, where M and N are greater than one. Each circuit device may have an output connected to a corresponding radiating element. Each submodule may include a power divider having K input ports and M output ports, where K is a factor of M. Each input port may be coupled to a corresponding receiving element, and each output port may be coupled to an input of a corresponding circuit device. Each submodule may include a heat spreader for removing heat from the circuit devices. The power source module may include a combination RF feed network and heat sink. The combination RF feed network and heat sink may include a wavefront expander to expand the RF input wavefront along at least one axis, and to direct the expanded wavefront to the receiving elements of the N submodules. The combination RF feed network and heat sink may also include a heat exchanger thermally coupled to the heat spreaders of the N submodules.

Modular MMW power source

An apparatus includes a microwave source that produces a microwave feed beam, and a first pair of microwave sensors that each intercept and receive a portion of the microwave feed beam. The two microwave sensors are spaced apart from each other along a first-pair axis. A first phase-comparison device has as it inputs the output signals of the two microwave sensors, and as an output a first phase comparison of the first-sensor output signal and the second-sensor output signal. A first geometrical calculator has as an input the first phase comparison and as an output a geometrical relationship of the first-pair axis to an other feature. This geometrical relationship output may be used to generate a control signal that is used to alter the geometrical relationship. There may be additional microwave sensors operating in a similar manner but spaced to provide information for other geometrical axes or allow improvements in geometrical measurements.

Apparatus and method using wavefront phase measurements to determine geometrical relationships

A high power slide tuning capacitor ( ) integrated into a circuit board adapted to function at RF and microwave frequencies. The capacitor ( ) includes a dielectric substrate ( ) with a cavity ( ) cut into a side of the substrate ( ); a ground plane ( ) mounted on a bottom surface of the dielectric substrate ( ); a microstrip patch ( ) mounted on a top surface of the dielectric substrate ( ) and positioned above the cavity ( ); and a movable dielectric stub ( ) which engages the cavity ( ) such that a variable length of the stub ( ) is positioned beneath the microstrip patch ( ). The microstrip patch ( ) can be coupled to a desired circuit trace ( ), effectively forming a shunt capacitor to ground.
