PROBLEM TO BE SOLVED: To provide a reflect array which can reflect an incident wave from a first direction in an arbitrary second direction.SOLUTION: In a reflect array having a plurality of elements arranged in the x-axis and y-axis directions and reflecting an incident wave in a desired direction, the ratio of the phase difference (&Dgr;α) of reflection wave from respective elements adjoining in the x-axis direction to the phase difference (&Dgr;α) of reflection wave from respective elements adjoining in the y-axis direction, out of the plurality of elements, is a predetermined value (γ), and the &Dgr;αand &Dgr;αare divisors equal to an integer multiple of 360 degrees. |
