1. A device for metamaterial array-based field-shaping, comprising:
a compartment sized to hold at least one object;
an array of phase array elements, each of the phase array elements comprising a metamaterial and configured to generate a plurality of waveform components;
one or more sensors configured to determine characteristics associated with the object at one or more spatial locations at multiple time points; and
a controller configured to determine parameters based on the characteristics determined at the multiple time points and to control application of at least one field comprising one or more of the waveform components at the at least one object by at least a portion of the phase array elements based on the parameters by individually controlling at least the portion of the phase array elements generating the one or more waveform components comprised in the field.
