Abstract: Perimeter control architectures for phased array antennas and metasurfaces are provided. A plurality of waveform emitters is disposed in an array having a plurality of rows and a plurality of columns. Each of the emitters is disposed within one of the plurality of rows and one of the plurality of columns. A plurality of column control lines is provided, each column control line interconnecting the emitters within one of the plurality of columns and adapted to provide a column control signal to the emitters within that column. A plurality of row control lines is provided, each row control line interconnecting the emitters within one of the plurality of rows and adapted to provide a row signal to the emitters within that row. A phase of each of the plurality of waveform emitters varies with the column control signal and the row control signal provided to that emitter, the plurality of waveform emitters remaining coherent.
