Title: Optimal Targeted Mode Transport in Complex Wave Environments: A Universal Statistical Framework
Authors: Wang, Cheng-Zhen, Guillamon, John, Kuhl, Ulrich, Davy, Matthieu, Reisner, Mattis, Goetschy, Arthur, Kottos, Tsampikos

Subject Terms: Physics - Optics
More Details: Recent advances in the field of structured waves have resulted in sophisticated coherent wavefront shaping schemes that provide unprecedented control of waves in various complex settings. These techniques exploit multiple scattering events and the resulting interference of wave paths within these complex environments. Here, we introduce the concept of targeted mode transport (TMT), which enables energy transfer from specific input channels to designated output channels in multimode wave-chaotic cavities by effectively engaging numerous cavity modes. We develop a statistical theory that provides upper bounds on optimal TMT, incorporating operational realities such as losses, coupling strengths and the accessibility of specific interrogating channels. The theoretical predictions for the probability distribution of TMT eigenvalues are validated through experiments with microwave chaotic networks of coaxial cables as well as two-dimensional and three-dimensional complex cavities. These findings have broad implications for applications ranging from indoor wireless communications to imaging and beyond.
