摘要： An isolating circuit for an electrosurgical generator arranged to produce radiofrequency (RF) energy and microwave energy for treating biological tissues is provided. The generator has an RF channel and a microwave channel which are combined at a signal combiner to enable the RF energy and microwave energy to be delivered into tissues along a common feed path. The isolating circuit includes a tunable wavelength isolator at a junction between the microwave channel and the signal combiner, and can include a capacitive structure between a ground conductor of the signal combiner and a conductive input section of the waveguide isolator to inhibit coupling of the RF energy and leakage of the microwave energy. The isolating circuit can combine into a single tunable unit all the necessary components to isolate the microwave and RF channels from one another while providing a high withstanding voltage.

摘要： A dielectric waveguide coupling system for launching and extracting guided wave communication transmissions from a wire. At millimeter-wave frequencies, wherein the wavelength is small compared to the macroscopic size of the equipment, transmissions can propagate as guided waves guided by a strip of dielectric material. Unlike conventional waveguides, the electromagnetic field associated with the dielectric waveguide is primarily outside of the waveguide. When this dielectric waveguide strip is brought into close proximity to a wire, the guided waves decouple from the dielectric waveguide and couple to the wire, and continue to propagate as guided waves about the surface of the wire.

摘要： Aspects of the subject disclosure may include, for example, a coupling device including a receiving portion that receives a radio frequency signal conveying data from a transmitting device. A magnetic coupler magnetically couples the radio frequency signal to a transmission medium as a guided electromagnetic wave that is bound by an outer surface of the transmission medium. A cap includes a dielectric portion that secures the transmission medium adjacent to the magnetic coupler and a reflective plate that reduces electromagnetic emissions from the magnetic coupler. Other embodiments are disclosed.
