Title:
NEGATIVE-REFRACTION IMPLEMENTATION METHOD USING PHOTO-MAGNON COUPLING AND CONTROL METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2024/014772
Kind Code:
A1
Abstract:
The present invention relates to a negative-refraction implementation method using photo-magnon coupling, and a control method therefor. The negative-refraction implementation method of the present invention implements negative refraction through photo-magnon coupling by using a photo-magnon hybrid system. The photo-magnon hybrid system comprises: a dielectric layer including a first surface and a second surface opposite to the first surface; microstrip lines arranged on the first surface and extending along the length direction; a first layer which is arranged on the second surface and excites a photon mode; and a second layer which is arranged on the microstrip lines and excites a magnon mode, wherein a negative refraction index signal is generated by the photo-magnon coupling of the first layer and the second layer.
