Matter and energy are delivered by superimposing multiple quantum wave states such that composite wave amplitudes are maximized at delivery target points and/or minimized at designated intermediate points. One or more target locations are identified for delivery of matter or energy waves, analyzing the medium along the transit path from the emitters, calculating interaction probabilities at each point along the medium, creating a scoring system for optimizing and limiting thresholds of interaction in designated regions; and calculating a combination of wave frequencies, emitter locations and vectors such that quantum interference between the beams optimizes the scoring outcome. The scoring system may be used to reward amplitudes within a specified range over a specified volume of space and penalized if the amplitude falls outside the range. The combined beam may be used for various purposes, including without limitation biological or military target compromise or elimination, electrical energy delivery, etc.

Beamformers are formed (e.g., carved) from a stack of transparent sheets. A rear face of each sheet has a reflective coating. The reflectivities of the coatings vary monotonically with sheet position within the stack. The sheets are tilted relative to the intended direction of an input beam and then bonded to form the stack. The carving can include dicing the stack to yield stacklets, and polishing the stacklets to form beamformers. Each beamformer is thus a stack of beamsplitters, including a front beamsplitter in the form of a triangular or trapezoidal prism, and one or more beamsplitters in the form of rhomboid prisms. In use, a beamformer forms an output beam from an input beam. More specifically, the beamformer splits an input beam into plural output beam components that collectively constitute an output beam that differs in cross section from the input beam.
