A novel approach to describe the properties of waveguides and circuits in photonic crystals was presented. It was demonstrated through the example of sharp waveguide bends that this approach was very accurate and effective for the study of bound states and transmission spectra of photonic-crystal circuits. It can be effective to study transmission in waveguide branches, channel drop filters and nonlinear localized modes in nonlinear waveguides.
