Megahertz Wave Control Components and Their Manufacturing Methods

Abstract

This invention provides a megahertz wave control element with novel optical properties and a method for manufacturing the same. The metamaterial 10 is a megahertz wave control element for optical control of megahertz waves, and includes a matrix 20 and a plurality of dielectric microparticles 30 dispersed within the matrix 20. The size of the dielectric microparticles 30 is below the wavelength of the megahertz wave. The specific refractive index of the matrix 20 relative to the megahertz wave is at least 2.0 smaller than the specific refractive index of the dielectric microparticles 30 relative to the megahertz wave.
