Abstract: Application of the adjoint method has proven successful in shape optimization and topology optimization. In the present chapter the adjoint method is applied to the optimization of eigenvalues and eigenmodes (eigenvectors). The general case of an arbitrary cost function depending on the first n eigenvalues and eigenmodes is detailed. The direct problem does not involve a bilinear form and a linear form as usual in other ...
