Combining the ATLM scheme with rotation of the polarization states of the mesh lines by 45$^\textrm\textbackslashcirc\$$ the computational effort can be reduced compared with conventional TLM by up to 75%. It is shown that by this way the conventional TLM scheme degenerates into four independent computational schemes, each of which contains the full information. Besides the reduction of the computational effort and storage requirements, also spurious modes and nonphysical solutions are eliminated.     «
