1. An electromagnetic wave propagation structure comprising:

  • a first element of dielectric material and a second element of dielectric material, the material of one of said first and said second elements having a high dielectric constant in excess of approximately 80, the material of the other one of said first and said second elements having a dielectric constant of less than approximately 2;

    wherein said first element is contiguous with said second element at an interface constituting a waveguide wall extending along a direction of electromagnetic propagation, said waveguide wall being part of a waveguide; and

    said interface is configured as a closed path as viewed in a cross sectional view of said waveguide.
