Zero crosstalk in anisotropic TM leaky mode with subwavelength grating metamaterials

We show that a TM leaky mode realized by subwavelength gratings (SWGs) can eliminate crosstalk between proximate waveguides. Oscillating fields i n t he SWGs allow coupling coefficient components to counteract each other, resulting in zero crosstalk.
