ELECTROMAGNETIC WAVE RESONATOR, METHOD OF MANUFACTURING SAME, AND ELECTROMAGNETIC WAVE GENERATOR ELEMENT EMPLOYING SAME

摘要

The main object of the invention is to provide an electromagnetic wave resonator making use of surface waves: an electromagnetic wave resonator structure capable of being achieved with existing technologies yet without much difficulty and applying voltage to a positive dielectric area, thereby overcoming a variety of problems arising from the fact that only thermal excitation is available. The contact structure of negative dielectric/positive dielectric/negative dielectric necessary for this type of electromagnetic wave resonator is provided on the surface of the negative dielectric material 1 just as the coaxial structure of the positive dielectric thin film 3 extending in the Y-axis direction and the negative dielectric material 2 received therein is cut in the axial direction. This makes sure both negative dielectric materials 1 and 2 with the positive dielectric thin film 3 sandwiched between them are electrically insulated so that voltage can be applied to the positive dielectric thin film 3, and ensures that an area provided in the negative dielectric material 1 to receive the positive dielectric thin film 3 has an aspect ratio D/P 1 of about 1.9, a figure well achievable in the state of the art.
