Abstract
The nonparaxial and bidirectional beam propagation method suitable for modelling high NA near-field and holographic optical storage systems is suggested for 2D geometry and TE polarization of the incident light beam. The complex Pade approximants are introduced for correct approximation of evanescent field in the near-field optics using pole-zero shifting in the complex plane. The application of bidirectional beam propagation method to study the multimode waveguide near-field focusing system and wide-angle beam Bragg reflection from volume holographic grating is considered.
