    摘要: A multi-beam reflectarray includes two or more element arrays including plural elements aligned along a predetermined direction. The multi-beam reflectarray is such that, in each of a first element group and a second element group included in at least one of the element arrays, a difference between phases of radio waves reflected by corresponding two elements is in proportion to a first product of a distance between the two elements and a value of a trigonometric function with respect to an angle of reflection by the two elements, and a distance between neighboring elements in the first element group is equal to a product of a rational number and a distance between neighboring elements in the second element group.

    摘要: A propagation path estimation method using an imaging method according to the invention includes a step of, in a case where a reflectarray which causes reflection and scattering in a different direction (θ−η)° from a specular reflection direction θ° exists on a propagation path from a transmission point to a reception point RX of the radio wave, calculating a virtual reception point VRX by rotating the reception point RX about a rotation center point O, and estimating the propagation path by using the virtual reception point VRX.
