Here, a curvilinear mixed-interpolation-type triangular-prism element is proposed so as to express cylindrical air holes of a photonic crystal slab smoothly enough in fewer elements. The numerical results are presented to show the usefulness of the analysis method., Copyright (c) 2006 by The Institute of Electronics, Information and Communication Engineers, application/pdf}, pages = {81--86}, title = {Curvilinear triangular-prism element for computation of band structure in photonic crystal slab}, volume = {3}, year = {2006} }
