Topology optimization for transient wave propagation problems in one dimension: Design of filters and pulse modulators

Research output: Contribution to journalJournal articleResearchpeer-review

Abstract

Structures exhibiting band gap properties, i.e., having frequency ranges for which the structure attenuates propagating waves, have applications in damping of acoustic and elastic wave propagation and in optical communication. A topology optimization method for synthesis of such structures, employing a time domain formulation, is developed. The method is extended to synthesis of pulse converting structures with possible applications in optical communication.
