摘要： A heat insulating transmission line includes a first waveguide with a first aperture end, a second waveguide with a second aperture end, and a reflector. The second waveguide is arranged coaxially with the first waveguide. The second aperture end faces the first aperture end through an air gap. The reflector is provided outside the air gap, and controls radiation power from the air gap. In addition, the reflector is substantially parallel to a portion of a virtual plane connecting an inner wall of the first aperture end of the first waveguide and an inner wall of the second aperture end of the second waveguide. When a mean frequency of a signal transmitting through the heat insulating transmission line is expressed as λ, a distance between the virtual surface and the reflector is not less than N×λ/2−0.05λ and not more than N×λ/2+0.2λ (N is a positive integer).

摘要： According to one embodiment, an electronic apparatus includes receiver circuitry, transmitter circuitry, and processor circuitry. The receiver circuitry receives a first signal including first data via a first frequency band. The transmitter circuitry starts transmission of a second signal via at least a part of the first frequency band. The processor circuitry reduces interference caused by the second signal to receive the first signal. The processor circuitry increases a power of the second signal until reducing the interference becomes stable for the first time since the transmitter circuitry has started transmission of the second signal.
