1. A metamaterial, comprising:
a plurality of flow sensors, each configured to sense a three dimensional vector flow state of a primary fluid wave in a medium and produce an electrical sensor signal in response;
a transducer, configured to emit a secondary fluid wave within the medium in response to an output, having a three dimensional vector flow state selectively dependent on the sensed three dimensional vector flow state of the primary fluid wave; and
an automated control, configured to:
receive the electrical sensor signal from each of the plurality of flow sensors;
perform a time and space transform on the electrical sensor signal from each of the plurality of flow sensors with an automated transform processor to determine a three dimensional spatial flow pattern of the primary fluid wave and a scattering of the primary fluid wave by an element; and
produce the output in accordance with a result of the time and space transform, to emit the secondary fluid wave which interferes with at least the scattering of the primary fluid wave.
