For an acoustic field in a waveguide, how would you take advantage of the orthogonality of normal modes to construct a modal, rather than plane-wave beamformer? Use a vertical array…..
In this situation what will you report?
You occasionally consult on justice system planning and operations, and have been contacted by a nearby county to examine its court functions. Apparently the former court administrator (Jameson) was very popular and considered efficient because he always operated within his rather meager budget. You discover, however, that those low operating costs were due to his notion that the court did not need any “fancy gizmos,” and thus the court’s staff struggles to perform the court’s daily functions with outmoded equipment. With Jameson now retired, the county manager (learning how antiquated the court’s functions really are), supports a major upgrade, and contacts you to learn of the available court technologies. What will you report?
