Abstract

In the following paper some different kinds of microwave guides will be inspected under main aspect of higher order modes. The knowledge of these modes is important for field matching problems at discontinuities and for suppressing propagation of higher order modes by geometrical variations. In some cases it is sufficient to know their principal behaviour. They will be calculated in paper by the often used orthogonal expansion. This method allows to determine all kinds of waves: propagating, damping and complex waves. The following guides are inspected:

  1. 1.

    rectangular waveguides,

  2. 2.

    circular waveguides,

  3. 3.

    L-shaped waveguides,

  4. 4.

    double ridged rectangular waveguides,

  5. 5.

    unilateral finlines with one slot,

  6. 6.

    unilateral finlines with two slots,

  7. 7.

    shielded microstrip lines,

  8. 8.

    circular image guides,

  9. 9.

    rectangular waveguides with dielectric slab,

  10. 10.

    H-guides.
