    • 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/P1 of about 1.9, a figure well achievable in the state of the art.
    • 本发明的主要目的在于提供一种利用表面波的电磁波谐振器:能够利用现有技术实现的电磁波谐振器结构,而且难以实现,并向正电介质区域施加电压,从而克服各种问题 这是因为只有热激发才能使用。 负电介质材料1的表面上设置这种电磁波谐振器所需负电介质/正电介质/负电介质的接触结构,正如正电介质薄膜3在Y轴方向上延伸的同轴结构 并且容纳在其中的负电介质材料2在轴向上被切割。 这确保了夹在其间的正电介质薄膜3的负电介质材料1和2被电绝缘,使得可以将电压施加到正电介质薄膜3,并且确保设置在负电介质材料1中的区域 接收正电介质薄膜3具有约1.9的纵横比D / P1,这在现有技术中可以实现。
