3. Microwave cavity - Wikipedia

   en.wikipedia.org/wiki/Microwave_cavity

   A microwave cavity or radio frequency cavity (RF cavity) is a special type of resonator, consisting of a closed (or largely closed) metal structure that confines electromagnetic fields in the microwave or RF region of the spectrum. The structure is either hollow or filled with dielectric material. The microwaves bounce back and forth between ...

4. Waveguide (radio frequency) - Wikipedia

   en.wikipedia.org/wiki/Waveguide_(radio_frequency)

   In radio-frequency engineering and communications engineering, a waveguide is a hollow metal pipe used to carry radio waves. [1] This type of waveguide is used as a transmission line mostly at microwave frequencies, for such purposes as connecting microwave transmitters and receivers to their antennas, in equipment such as microwave ovens, radar sets, satellite communications, and microwave ...

5. Waveguide flange - Wikipedia

   en.wikipedia.org/wiki/Waveguide_flange

   The through-mounted assembly is made evident by the distinct colours of the copper waveguide-tube and brass flange. A waveguide flange is a connector for joining sections of waveguide, and is essentially the same as a pipe flange—a waveguide, in the context of this article, being a hollow metal conduit for microwave energy.

6. Isolator (microwave) - Wikipedia

   en.wikipedia.org/wiki/Isolator_(microwave)

   At microwave frequencies, this material is usually a ferrite which is biased by a static magnetic field [1] but can be a self-biased material. [2] The ferrite is positioned within the isolator such that the microwave signal presents it with a rotating magnetic field, with the rotation axis aligned with the direction of the static bias field.

7. Waffle-iron filter - Wikipedia

   en.wikipedia.org/wiki/Waffle-iron_filter

   An illustrative cutaway of a typical waffle-iron filter design. A waffle-iron filter is a type of waveguide filter used at microwave frequencies for signal filtering.It is a variation of the corrugated-waveguide filter but with longitudinal slots cut through the corrugations resulting in an internal structure that has the appearance of a waffle-iron.
