DIELECTRIC WAVEGUIDE WINDOW
Dielectric windows are used when it is desired to to another, but to maintain a gas-tight seal between the two parts. Existing dielectric windows comprise irises so dimensioned as to be resonant at the operating dvantage that the thickness of the dielectric material must be controlled to within close limits. The dielectric illed along a portion of its lenght with dielectric material, the cross-sectional dimensions of the wave-guide being related to the operating frequency and the dielectric constant of material insuch a way as to maintain the same impedence to E-mode waves in filled and the window is determined by mechanical considerations. The use is restricted to modes of waveguide propagation having transverse magnetic fields, i.e. E-mode waves, but conventional forms of waveguide transformer can be used on either side of the window if other modes of propagation are desired.
