文摘

In this paper we design polarization transformers using transformation electromagnetics method. We introduce a new coordinate transformation that by compressing or expanding the space, creates a desired delay on one component of electromagnetic fields and therefore causes the polarization of electromagnetic wave to change. Linear to circular, right (left) hand to left (right) hand circular and linear to linear polarization transformers have been designed and analyzed. The proposed polarization transformers are homogeneous and reflectionless and they can also be non-magnetic. COMSOL Multiphysics software is used to validate our results.
