. This paper presents a method Qf eigenvalue calculation related to periodic boundary va ユ ue problems f{)r the Helmholtz eqllation in two dimensiQns based on the Sakurai − Sugiura projection method and periodic FMM . The Sakurai − Sugiura projection method solves nonlinear eigenvalue problem8 using contour integrals and is considered to be suitable for solving eigenvalue problems in conjuction with bol1 皿 dary elemen 七 methods . We apply this method to eigenvalue prQblems specific to periodic
