Homes typically have several kinds of home wiring, including electrical wiring for lighting and power distribution, permanently installed and portable appliances, telephone systems, heating or ventilation system control, and increasingly for home theatre and computer networks.
At microwave frequencies, the types of cable (transmission line) used to conduct lower frequency radio waves, such as coaxial cable, have high power losses. Therefore, to transport microwaves between the transmitter or receiver and the antenna with low losses, a special type of metal pipe called waveguide must be used.

He investigated cooking with microwaves and invented the microwave oven, consisting of a magnetron feeding microwaves into a closed metal cavity containing food, which was patented by Raytheon on 8 October 1945. Due to their expense microwave ovens were initially used in institutional kitchens, but by 1986 roughly 25% of households in the U.S ...
Installing electrical wiring by "chasing" grooves into the masonry structure of the walls of a building. Materials for wiring interior electrical systems in buildings vary depending on: Intended use and amount of power demand on the circuit; Type of occupancy and size of the building; National and local regulations
A microwave oven or simply microwave is an electric oven that heats and cooks food by exposing it to electromagnetic radiation in the microwave frequency range. [1] This induces polar molecules in the food to rotate and produce thermal energy (heat) in a process known as dielectric heating .
The gap thus forms a quarter-wave transformer, transforming the high impedance at the top of the ditch to a low (ideally zero) impedance at the broad wall of the waveguide. [citation needed] Figure 4. Plastic caps over disconnected flanges prevent dirt [4] and moisture entering the waveguide, in addition to protecting the face of the flange ...
Wireless light switches eliminate the wire from the light to the switch location. This is useful in remodelling situations where new wiring can be a hassle. Rather than tearing down a wall to gain access to the wires, a wireless switch can be used.
