- the relative dielectric constant of the portion of the dielectric medium 30 can be adjusted to an arbitrary value by changing the irradiation amount of the electron beam.
- a dielectric line was manufactured in the same manner and under the same conditions. Built. In this case, the relative dielectric constant of the portion of the dielectric medium 30 was 1.8. In this way, it is possible to change the relative dielectric constant of the portion of the dielectric medium 30.
- the space between the two conductor plates is filled with the dielectric strip and the dielectric medium, so that the portion other than the dielectric strip becomes a space (air).
- the displacement of the dielectric strip is less likely to occur, and the strength is dramatically improved, resulting in a stable structure.
- the dielectric constant and the dielectric loss can be extremely reduced by increasing the porosity, so that a very high transmission efficiency of a high-frequency signal can be achieved. It is possible to transmit with low loss.
- the dielectric medium and the dielectric medium can be manufactured from one kind of material by forming the dielectric medium and the dielectric medium with substantially the same material.
- manufacturing becomes easier (manufacturing cost is reduced), and it is possible to manufacture using a patterning process. Therefore, it is more suitable for mass production than the conventional case of manufacturing a three-dimensional structure by mechanical processing. As a result, it can be easily processed into complicated shapes.
