PROBLEM TO BE SOLVED: To provide an electromagnetic wave element that reduces an influence of aberration on electromagnetic waves of a plurality of bands having significantly different wavelengths, with a simple structure.SOLUTION: An electromagnetic wave element is configured by a composite dielectric in which a second dielectric 2 having a different dielectric constant from a first dielectric is dispersed in the first dielectric 1. The electromagnetic wave element has an effective dielectric constant almost equal to the electromagnetic wave of a predetermined first wavelength and that of a predetermined second wavelength longer than the first wavelength. The average particle size and average interspace of the second dielectric 2 is smaller than the first wavelength. |
