The experimental realization of a multiple-input, multiple-output (MIMO) metastructure for antenna beamforming is reported. The metastructured beamformer is designed using a recently reported ...

A comprehensive analysis is presented for investigating the effects of input nonlinearity on performance and broadband design of continuous-mode class-F power amplifiers (PAs). New time-domain ...

Up front, there’s a single quarter-inch headphone jack, a generously sized volume knob with satisfying resistance, and an input selector switch that clicks with a mechanical precision that makes using ...
