The advent of very broad band microwave amplifiers and oscillators necessitates microwave circuitry of comparable frequency range. A scheme is presented which makes it possible to build microwave couplers of various kinds having bandwidths of well over two octaves. A preliminary investigation of mechanical and mathematical analogs is described; and some particular devices using the new principle are mentioned.
