Claims4
A non-radiative dielectric line assembly, comprising:
- a first non-radiative dielectric line of a first type, comprising a dielectric strip between two approximately parallel conductive planes, in which a space between said conductive planes is approximately equal to a height of said dielectric strip;
- and
- a non-radiative dielectric line of a second type, comprising a dielectric strip between two approximately parallel conductive planes,
- in each said non-radiative dielectric line, an area defined by said dielectric strip being a propagation area for an electromagnetic wave, and an area other than said area defined by said dielectric strip being a non-propagation area,
- in said non-radiative dielectric line of said second type, said space between said conductive planes in said non-propagation area being smaller than said space between said conductive planes in said propagation area, and a cut-off frequency of an LSM01 mode that propagates in the propagation area being lower than a cut-off frequency of an LSE01 mode, whereby only said LSM01 mode propagates,
- said first dielectric line of said first type being electromagnetically coupled to said dielectric line of said second type;
- and
- further comprising a second dielectric line of said first type, said first and second dielectric lines of said first type defining a non-radiative dielectric line switch that switches between propagation and non-propagation of said electromagnetic wave by varying a facing alignment of said first and second non-radiative dielectric lines of said first type.
