HIGH-FREQUENCY ELECTROMAGNETIC WAVE TRANSMISSION LINE

摘要

PROBLEM TO BE SOLVED: To provide a high-frequency electromagnetic wave transmission line usable even in a frequency domain higher than that of a metal waveguide. SOLUTION: The high-frequency electromagnetic wave transmission line 1 has a core 11 having a higher dielectric constant than the surroundings 12. When an incident angleθ0to the boundary face 13 of the core 11 and the surroundings 12 is larger than a critical angle, an electromagnetic wave propagated inside the core 11 is totally reflected with the boundary face 13. Therefore, the electromagnetic wave does not leak to the surroundings 12 and is confined inside the core 11. The high-frequency electromagnetic wave transmission line 1 can be very easily manufactured since it does not have a hollow structure. The low-loss transmission line can be realized by forming the high-frequency electromagnetic wave transmission line 1 by using a material with a smaller loss in a high-frequency domain.
