Latest Patents

Dupuy holds a patent for "Power combiners using meta-material composite right/left hand transmission line at infinite wavelength frequency." This invention describes power combining methods and devices for tunnel diode oscillators that utilize the infinite wavelength phenomenon observed in composite right/left-handed (CRLH) meta-material lines. One implementation features a series combiner composed of zero-degree lines, where each oscillator output port is directly connected to the line and combined in-phase, allowing for equal power combination. Another implementation involves a stationary wave resonator with oscillators loosely coupled to the resonator, maintaining constant wave amplitude and phase along the line. In tests of this second implementation, a maximum power combining efficiency of 131% was achieved with a zero-order resonator using two tunnel diode oscillators at 2 GHz.
