H01P WAVEGUIDES; RESONATORS, LINES, OR OTHER DEVICES OF THE WAVEGUIDE TYPE (operating at optical frequencies G02B)
Introduced: September 1968
Description
H01P covers the design, construction, and components of waveguides and waveguide-based devices used to transmit electromagnetic waves, primarily in microwave and millimeter-wave frequency ranges. This includes hollow metallic waveguides, coaxial transmission lines, dielectric waveguides, and integrated waveguide structures on circuit boards or substrates. The class encompasses resonators, filters, couplers, junctions, bends, and other passive microwave components that guide, modulate, or control electromagnetic energy propagation. Related transmission line technologies and antenna feed systems are also included within this classification's scope.
