Abstract:
1. A dielectric waveguide, comprising: a first single crystal magnesium oxide block having an input face of orientation (001), (100) or (010), and having other faces each of orientation (001), (100) or (010); a first copper oxide superconducting film disposed on each of said other faces of said first single crystal magnesium oxide block in a c-axis crystal orientation perpendicular to the face of said block on which it is disposed; a second single crystal magnesium oxide block having a face of orientation (001), (100) or (010); and a second copper oxide superconducting film disposed on said face of said second single crystal magnesium oxide block in a c-axis crystal orientation perpendicular to said face of said second single crystal magnesium oxide block, wherein said first single crystal magnesium oxide block has a further face oriented at a 45 degree angle to said input face, so that the further face has orientation (011), (101) or (110), and said second copper oxide superconducting film comes in contact with said further face oriented at a 45 degree angle of said first single crystal magnesium oxide block.
