The present disclosure relates to a computer system for maximizing wireless energy harvesting using an intelligent reflection surface and a method thereof. A multi-path channel including a direct channel through which power is directed from an ET apparatus toward an EU apparatus and a reflection channel through which the power is directed from the ET apparatus toward the EU apparatus after being reflected by an IRS apparatus may be implemented. The computer system may be designed to maximize a gain of the multi-path channel in order to maximize the harvested power.
