Title:
DEVICE FOR CONVERTING FREQUENCY OF ELECTROMAGNETIC WAVE
Document Type and Number:
WIPO Patent Application WO/2022/124756
Kind Code:
A1
Abstract:
The present invention relates to a device for converting a frequency of an electromagnetic wave and, more specifically, to a device for converting an original frequency of an electromagnetic wave into a frequency corresponding to a resonator mode by using a time-varying Fabry-Perot resonator including a time-varying reflective surface of which reflectivity changes with time. A device for converting a frequency of an electromagnetic wave according to an embodiment of the present invention comprises: a time-varying reflective surface on which an electromagnetic wave is incident and of which reflectivity changes with time; and a partially reflective surface which is disposed at a predetermined distance from the time-varying reflective surface, from which an electromagnetic wave having a frequency corresponding to a resonator mode is emitted, and which has a fixed reflectivity for partially reflecting the electromagnetic wave incident through the time-varying reflective surface, wherein the reflectivity of the time-varying reflective surface is smaller than the reflectivity of the partially reflective surface, and after the electromagnetic wave is trapped between the time-varying reflective surface and the partially reflective surface, the reflectivity of the time-varying reflective surface becomes greater than the reflectivity of the partial reflective surface.
