Systems, methods, and media for wireless power transfer are provided. In some embodiments, a system for wireless power transfer comprises: a processor communicatively coupled with a tuning element and a plurality of ports in an enclosure, the processor configured to cause the ports to generate electromagnetic radiation at a first frequency, set the tuning element to a first setting, acquire electromagnetic response from the ports, determine an S-matrix using the electromagnetic response, determine an eigenvalue of the S-matrix, repeat these steps (changing the first frequency and/or first setting) at least until the determined eigenvalue is approximately zero, determine a resolved electromagnetic radiation frequency and a resolved tuning element setting having the approximately zero eigenvalue, determine an eigenvector associated with the resolved electromagnetic radiation frequency and resolved tuning element setting, and cause the ports to generate the electromagnetic radiation at the resolved frequency with phase and amplitude determined from the eigenvector.
