Abstract
A method of focusing radio wave energy at a focusing target point, which is performed by a processor, may comprise: generating an electromagnetic numerical model of an object including the focusing target point; predicting radio wave focusing points inside the object using radio wave characteristic information of a radio wave radiation module and the electromagnetic numerical model; optimizing one or more focusing parameters such that radio wave energy reaching one or more unnecessary focusing points other than the focusing target point among the radio wave focusing points inside the object is reduced; and radiating radio waves based on the optimized focusing parameters.
