As motivation, a phononic bandgap design problem is first developed and attempted using a pixel filling approach. Though decent results are achieved, the possible solutions are inherently limited by the geometric representation. The new method is then introduced and applied to the inverse scattering of conducting cylinders. Subsequently, homogeneous and inhomogeneous dielectric inverse scattering problems are solved and the efficiency of the method is addressed using local search methods. Finally, several advances in electromagnetic solvers, specifically time domain Nystrom methods, are reported. These methods offer advantages over other competing methods and could be used with different geometry design problems.Chapter 2 GEOMETRY OPTIMIZATION APPLICATION: BANDGAP STRUCTURES Geometry optimization is necessary in a large number of design problems. As an introduction to such problems, the design of phononic bandgap materials isanbsp;...
