摘要： A system and method includes a waveguide for guiding an energy received from a laser. A resonator couples with the waveguide. A signal generator (pump) generates a spatiotemporal pattern wave in the resonator. The spatiotemporal pattern wave produces a wave interaction. Where an interaction between the signal, the spatiotemporal pattern wave and the wave interaction produce linear non-reciprocal behavior in the signal wave.

摘要： A noise suppression structure for suppressing an undesired high-frequency current in a transmission line (i.e. a sleeve) of a short-circuited termination type includes a conductor base encompassing the periphery of the transmission line and a conductor short-circuiting part which is connected to the transmission line at the opposite side to an open end of the conductor base and whose inductance is greater than that of the conductor base. It is possible to increase an inductance by modifying the shape of the terminal end of the sleeve, equivalent to a quarter wavelength of an undesired high-frequency current which occurs in a wireless circuit of a mobile wireless terminal and flows through a ground layer, thus reducing the entire length and realizing miniaturization while securing desired input impedance.

摘要： A multilayer dielectric evanescent mode waveguide bandpass filter with resonators utilizing via hole technology is capable of achieving very narrow bandwidths with minimal insertion loss and high selectivity at microwave frequencies is provided. A typical implementation of this filter is fabricated with soft substrate multilayer dielectrics with high dielectric constant ceramics. This filter typically takes up less space than other filters presently available. A typical implementation operates at a center frequency of 1 GHz, although other center frequencies, such as approximately 0.5 GHz to approximately 60 GHz, are achievable.

摘要： The invention relates to ultra-high frequency filters with variable capacitance tuning devices tunable in a wide frequency range.Each tuning device comprises two coaxial fingers, namely a fixed finger and a finger movable in the filter body. One of these fingers is hollow and the other has a tuning plunger, whose end is cylindrical and which is displaceable, e.g. by screwing in the body of the finger. The minimum capacitance obtained with a minimum penetration of the plunger, its end being level in the vicinity of the end of the corresponding finger, is adjustable by displacing the movable finger relative to the fixed finger. The supplementary variable capacitance is obtained by plunging the tuning plunger into the hollow finger.

摘要： This invention relates to waveguide filters wherein waveguide sections functioning in the evanescent mode for frequencies in the desired passband are utilized to couple conventional cavity filter sections together. The evanescent sections operate in their normal modes at frequencies higher than the passband frequencies. Suppression devices are then coupled to one or more of the evanescent sections (instead of to the cavity filter sections) to suppress the parasitic harmonic waves while having negligible effect on the evanescent mode passband frequencies.
