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. 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. The channeled transformer can simultaneously transform multiple arbitrary wavefields as is the case with many traditional optical devices, but channels can be controlled to enable new variations of such devices. Channels allow flexibility in positioning of the input and output surfaces. When used with ultrasonic wavefields, electrical channels can be freely arranged while ignoring path lengths in the channels. In general, the channel system allow insertion of general electrical networks that can include a variety of signal processing devices. Channels may carry continuous signals or sampled signals. Switching devices change channel connections to quickly modify the configuration. The channeled wavefield transformer enables devices that extend from coherent television to high power industrial systems.
