The conditions for appearance of the isoscattering points of one‐ and two‐dimensional systems have been theoretically derived using the ideal models of oriented membranes and fibers. The position s * of the isoscattering point of a one‐dimensional system is given by s * = n /(2 R 0 ), where n is a positive integer and 2 R 0 is the thickness of the membrane. For a two‐dimensional system, the position s * is given by J 1 (2 πs * R 0 ) = 0, where J 1 is the first‐order Bessel function and R 0 is the radius of the fiber.
