Abstract	:	This work is concerned with the numerical solution of Maxwell's equations. Theemphasis is on the study of approximate techniques for truncation of unboundeddomains. The original contribution of this study is the treatment. adaptation. analysis andimplementation of absorbing boundary conditions using perfectly matched layen in thefrequency domain using finite element methods. Previous works have been mainlyconcerned with the finite difference methods with no foundation to justify truncating theunbounded domains with perfect matched layers with absorbing boundary conditions.With this goal, weak formulations for the curlturl wave equation are studied inthe context of scattering problems. The finite element method framework is used todiscretize the weak formulas. In particular, edge vector....-....,....-...,..tested for theQ1 PC1 bus cardBoth these projects mere sofixare des elopment efforts tonards contributing to dlfferentaspects of Roboucs and lZ1echatronics projects m the Controls and Roboucs Group..
