A three‐dimensional unconditionally stable five‐step locally one‐dimensional finite‐difference time‐domain (LOD‐FDTD) method for anisotropic magnetized plasma medium is presented. Firstly, we search for a diagonal matrix to transform Maxwell coefficient matrix of plasma into skew symmetric matrix wh...
