Winches with integrated lighting, and associated systems and methods are disclosed. A representative winch with integrated lighting can include a frame, a cable drum rotatably supported by the frame, a drive motor operatively connected to the cable drum, and an electrical module. The electrical module can include a housing with first and second end caps coupled to the housing. An elongate light guide can be mounted to the housing between the housing and the cable drum with one or more drum light sources connected to the elongate light guide.

Systems and method are provided for implementing filters whose response automatically and continuously reconfigures between an all-pass response and a bandstop response as the power level of signals within their bandwidth changes. Embodiments of the present disclosure allow high power signals within a designable bandwidth to be strongly attenuated while minimally affecting signals in adjacent bandwidths and further allow low power signals in the designable bandwidth to pass with minimal attenuation.

A 2-bit high-power amplifying non-reciprocal reflective metasurface is provided. The metasurface comprises a plurality of metasurface units distributed in an array; each metasurface unit comprises a first metal layer, an intermediate layer, and a second metal layer which are sequentially stacked; the second metal layer comprises a receiving metal patch and a transmitting metal patch; two diodes are both positioned on a longitudinal central axis of the receiving metal patch; orientation of the slot on the transmitting metal patch is orthogonal to orientation of the slot on the receiving metal patch; the first metal layer comprises a phase shifter, which comprises first series diodes and second series diodes forming a reconfigurable 90-degree phase-shift circuit.
