Abstract
A device converting cylindrical waves to plane waves is demonstrated. This device is comprised of two Luneburg lenses and Bragg gratings. The two Luneburg lenses are placed in contact with each other and Bragg grating is placed perpendicular to the longitudinal axis of the lenses. The function of the Luneburg lens is to convert cylindrical waves to plane waves and vice versa. The function of the Bragg grating is to reflect the plane waves. If we put the cylindrical wave source on the contact point of the lenses, short range plane waves are generated. We verified them by using the FEM simulations. Efficiency of the device is also analyzed depending on wavelength and dimension of the lens.
