A representation of acoustic waves in unbounded domains

Bradley K. Alpert, Yu Chen

Research output: Contribution to journalArticlepeer-review


Compact, time-harmonic, acoustic sources produce waves that decay too slowly to be square-integrable on a line away from the sources. We introduce an inner product, arising directly from Green's second theorem, to form a Hubert space of these waves and present examples of its computation.
