In this paper, the optimization of the power transfer over wireless channels having multiple-inputs and multiple-outputs (MIMO) is studied. As a result, an optimization framework is proposed, which yields the maximum achievable power transfer efficiency over a given MIMO channel and the corresponding operating point, i.e., the complex amplitudes of the optimal incident and reflected waves. The optimization framework can be used to gain insights in the WPT over arbitrary MIMO channels.

Nowadays, faced with the ever-increasing dependence on diverse electronic devices and systems, the proliferation of potential electromagnetic interference (EMI) becomes a critical threat for reliable operation. A typical issue is the electronics working reliably in power-line networks when exposed to electromagnetic environment. In this paper, we consider a conducted ultra-wideband (UWB) disturbance, and perform the impact evaluation at the loads in a network.
