Abstract
Described embodiments include a system and method. An antenna is configured to implement at least two selectable radiative electromagnetic field spatial distributions. Each selectable radiative electromagnetic field spatial distributions respectively has a bounding surface that describes a specified power density in the radiative electromagnetic field. A sensor circuit is configured to detect a presence of an object within the bounding surface of an implemented radiative electromagnetic field. A countermeasure circuit is configured to select a response to the detected presence of the object within the bounding surface of the implemented radiative electromagnetic field. A spatial distribution selector circuit is configured to select from the at least two selectable radiative electromagnetic field spatial distributions another radiative electromagnetic field spatial distribution (i) that includes a target device present within the bounding surface of the selected radiative electromagnetic field and (ii) that implements the selected response to the detected presence of the object.
