In this paper, a wideband flat lens antenna with low reflection and good performance is presented based on conformal transformation optics (CTO). Physical space optimization is applied to eliminate singular refractive index values. Furthermore, we em

In this paper, we design an implementable high-performance flat reflector based on conformal transformation optics. In the proposed 2-dimensional device, the rescaling refractive index approach is applied to overcome the sub-unit refractive index iss

In this paper, transformation optics is used to design a new wave transformer that converts a cylindrical wave to a plane wave. For this purpose, we consider a new coordinate transformation in which the resulting wave transformer will be reflectionle

In this article, a new leaky wave antenna (LWA) based on modified substrate integrated waveguide (SIW) is introduced. At first, the modified SIW structure is presented and it is shown that it supports propagation of quasi-TEM with nearly uniform elec
