    en.wikipedia.org/wiki/Microwave_spectroscopy

    For insulating materials (both solid and liquid), [6] probing charge dynamics with microwaves is a part of dielectric spectroscopy.Amongst the conductive materials, superconductors are a material class that is often studied with microwave spectroscopy, giving information about penetration depth (governed by the superconducting condensate), [4] [7] energy gap (single-particle excitation of ...

    L E is the slant height of the side in the E-field direction L H is the slant height of the side in the H-field direction d is the diameter of the cylindrical horn aperture L is the slant height of the cone from the apex λ is the wavelength. An optimum horn does not yield maximum gain for a given aperture size.

  6. Super high frequency - Wikipedia

    en.wikipedia.org/wiki/Super_high_frequency

    Super high frequency (SHF) is the ITU designation [1] [2] for radio frequencies (RF) in the range between 3 and 30 gigahertz (GHz). This band of frequencies is also known as the centimetre band or centimetre wave as the wavelengths range from one to ten centimetres.

  7. Microwave transmission - Wikipedia

    en.wikipedia.org/wiki/Microwave_transmission

    Microwave signals are normally limited to the line of sight, so long-distance transmission using these signals requires a series of repeaters forming a microwave relay network. It is possible to use microwave signals in over-the-horizon communications using tropospheric scatter , but such systems are expensive and generally used only in ...

  9. Q band - Wikipedia

    en.wikipedia.org/wiki/Q_band

    The Q band is a range of frequencies contained in the microwave region of the electromagnetic spectrum. Common usage places this range between 33 and 50 GHz, but may vary depending on the source using the term. [1] [2] The foregoing range corresponds to the recommended frequency band of operation of WR22 waveguides.
