Abstract

PURPOSE: To focus reflected waves in different directions without any distortion by providing comb-tooth-form parallel grooves or protrusions on the mirror face of a concave mirror concerning the reflecting mirror which is used in the frequency regions from microwaves up to light.
CONSTITUTION: The envelope curve 8 of the vertex parts of the grooves 6 parallel to the plane of the figure is formed by subsequently connecting the points of intersection of the incident rays and reflected rays where the angles that they assume with optical axes 3, 4 are equal. Next, the envelope curve 7 of the bottom of the grooves 6 is set by determining such depths of the grooves as to correct the deviations in the electric length of each ray. In addition, the distance d of the grooves 6 is made sufficiently shorter than the wavelengths and the direction of electric fields is made parallel to the plane of the figure. Thereby, the distortion-free reflecting mirror may be realized and may be utilized as the transmission path of less transmission losses in millimeter waves.
