Linear polarizer made of indefinite media

We propose a new type of polarizer that utilizes indefinite media–media for which not all elements of the permittivity and permeability tensors possess the same sign . We demonstrate both theoretically and numerically that, when certain physical parameters are chosen, a slab of indefinite media can transmit all the p-polarized components of the incident electromagnetic waves and fully reflect the s-polarized ones; thus, it can be used as a linear polarizer or a polarizing beam splitter. The proposed polarizer has some advantages compared to polarizers of the conventional types. Practical models for such polarizers are also presented.
