WIRELESS POWER TRANSMISSION BASED ON PRE-MATCHED FILTERING

A method of focused wireless power transmission is disclosed which includes generating a map for electromagnetic fingerprints at N locations within an environment of interest, including a transmitter and plurality of receivers each located at one of the N locations, transmitting pre-matched signals based on the electromagnetic fingerprints in a predetermined order for a first location of the N location, measuring response at each of the N locations, measuring spatial correlations between all other locations and the first location, and evaluating electromagnetic power focus at each of the N locations by comparing the measured spatial correlations.
