Abstract: Technology is disclosed herein for a system, devices, and methods for microwave focusing in various implementations. In an implementation, a computing device identifies a location for receiving focused microwave emissions from an array of antennas. The computing device determines an optimal antenna configuration for illuminating the location by the microwave emissions based at least on a configuration of the array and causes the antennas to illuminate the location according to the optimal antenna configuration. In an implementation, the computing device determines the optimal antenna configuration for illuminating the location based on a spatial distribution of material properties of a volume which includes the location. In an implementation, the spatial distribution is based on imaging data of the volume. In various implementations, the configuration of the array includes a spherical or cylindrical distribution of antenna positions.

Abstract: An improved fuse element for use in a circuit protection fuse. The fuse element may include an insulating substrate portion and a conductive metallic portion disposed on at least one surface of the insulating substrate portion, wherein the metallic portion extends along, and is in continuous, intimate contact with the substrate portion. When the metallic portion melts and separates upon the occurrence of an overcurrent condition, the substrate portion bridges the resulting gap that is formed in the metallic portion and provides electrical arc suppression therein.
