Abstract: An electromagnetic flux controlling member includes a first region disposed on a rear side, and configured to allow incidence of electromagnetic waves or to emit to outside electromagnetic waves having travelled inside, and a second region disposed on a front side, and configured to emit to the outside the electromagnetic waves entered from the first region or to allow incidence of electromagnetic waves. The second region includes a plurality of circular parts concentrically disposed in plan view, outer edges of the plurality of circular parts are disposed such that the outer edges of the plurality of circular parts come closer to the rear side with increasing distance from a central axis side, and widths of at least some circular parts adjacent to each other of the plurality of circular parts are the same, and are smaller than a wavelength of the electromagnetic waves.

Abstract: An electromagnetic flux controlling member includes an incidence surface for allowing incidence of an electromagnetic wave, and an emission surface for emitting the electromagnetic wave incident on the incidence surface to an outside. At least one of the incidence surface and the emission surface includes a base curved surface and a plurality of protrusions arranged on the base curved surface. Each of the plurality of protrusions includes a conical tip portion disposed such that at least a part of an edge of a bottom surface of the conical tip portion makes contact with the base curved surface, and a partially columnar leg portion disposed between the conical tip portion and the base curved surface. A central axis of the conical tip portion and a central axis of the partially columnar leg portion are parallel to a main axis of the electromagnetic flux controlling member.
