Modelling and measurement of cascaded tensor impedance surfaces for polarization control

Polarization control of the electromagnetic field is an important aspect of many communication systems. One method of controlling polarization is through the use of chiral effects. This includes circular polarization selectivity and linear polarization rotation. These kinds of effects can be implemented in many ways including stacks of meander-line polarizers (M. Joyal and J. Laurin, IEEE Trans. on Antennas and Propagation, vol. 62,no. 6, pp. 30433053, June 2014 ). However, designing these surfaces using cascaded tensor impedances is a viable alternative that can minimize their physical footprint. Such designs consist of tensor impedance surface cascaded back to back as shown in Fig. 1.
