This problem is first reformulated as a two by two boundary system of boundary integral equations. Next, utilizing the Schur complement technique, we develop a Schur complement operator with regularization to obtain a reduced system of boundary integral equations. The Nystr\\\"{o}m discretization is then used to obtain an eigenvalue problem for a matrix. We employ the recursive integral method for the numerical computation of the matrix eigenvalue. Numerical results show that the proposed method is efficient and reduces computational costs.", "revisions": [ { "version": "v1", "updated": "2021-03-01T03:23:34.000Z" } ], "analyses": { "keywords": [ "boundary integral operators", "regularized schur complement", "transmission eigenvalues", "boundary integral equations", "reduces computational costs" ], "note": { "typesetting": "TeX", "pages": 20, "language": "en", "license": "arXiv", "status": "editable" } } }
