ABSTRACT:
The channeled wavefield transformer enables multi-dimensional wavefield signal processing which leads to significant expansion of the engineering field of electronic signal processing. The term “wavefield” is used to indicate one or more waves that operate in at least two dimensions of space where spatial form of a wave can be represented by a wavefront that is a surface of points of equal phase. This transformer produces an output wavefield in a clear medium in response to an arbitrary input wavefield. This is carried out using multiple channels that connect input sensing devices to respective output transmitting devices, through general electrical or optical networks. The input devices are arranged along an input surface and the output transmitting devices are arranged along an output surface. An output wavefield emerges from the output surface to propagate in an output wavefield space.
