Abstract
We present a semi-analytical method for accurate modeling of wave propagation in cylindrically symmetric subwavelength metal-dielectric multilayers. Utilizing a cylindrical transfer matrix method, we compute the amplitude transfer function of cylindrical hyperlens, simulate the exact field distribution and propagation for a given source and compare it to that in effective hyperbolic medium.Weinvestigate the conditions under which the effective medium theory (EMT) is valid and show that in cylindrical configuration, a new degree of freedom is present in the applicability of the EMT-the ratio between the inner radius of the structure and the unit cell size.
