Abstract:
A selective frequency limiter having a magnetic material and a slow wave structure disposed to magnetically couple a magnetic field, produced by electromagnetic energy propagating through the slow wave structure, into the magnetic material.
Abstract:
Radar systems and methods detecting and tracking an unmanned aerial system (UAS) are provided. The radar system and methods can include determining whether or not a UAS is included in the plurality of electromagnetic signals received by the radar system based on one or more expected frequencies that one or more UAS devices use to transmit signals to remote controls. The radar systems and method can also involve switching the radar system into a track mode upon detecting a UAS.
Abstract:
A system includes a UV light source and an optical medium coupled to receive UV light from the UV light source. The optical medium is configured to emit UV light proximate to a surface from which biofouling is to be removed once the biofouling has adhered to the protected surface. A method corresponds to the system.
