We propose a half-cylindrical hyperlens with symmetrical metallodielectric structure which consists of five periods of the symmetrical GaP/Ag/GaP films. Such hyperlens can transfer subwavelength information to the output surface (about one wavelength) due to the flat dispersion. Compared with the ha...
