A new approach to calculating Floquet spectra of multilayered periodic waveguides is presented. The problem is formulated as an eigenvalue problem of the Helmholtz equation on an infinite strip with discontinuous wavenumber. The strip is decomposed into a rectangle and two semi-infinite domains, and
