A striking prediction from the random matrix theory (RMT) in mesoscopic physics is existence of “open channels”: waves that use multipath interference to achieve perfect transmission across an opaque disordered medium even multiple-scattering regime. Realization such open channels requires a coherent control complete incident wavefront and has only been achieved for scalar two dimensions (2D) so far. Here, we utilize recently proposed “augmented partial factorization” full-wave simulation method compute polarization-resolved scattering 3D vectorial Maxwell’s equations demonstrate media. We examine spatial profile channels, bimodal eigenvalue distribution, study effects incomplete polarization finite-area illumination. The simulations provide full access all spatiotemporal properties complex wave transport systems, filling gap left by experimental capabilities.
