A method for generating enhanced evanescent Bessel beam is reported. When a radially polarized beam is strongly focused onto the last interface of one-dimensional photonic band gap structure, enhanced evanescent J(0) type Bessel beam can be generated via the band-edge resonance. Similarly, enhanced evanescent J(1) type Bessel beam can be created by reversing the multilayer structure under azimuthally polarized illumination. These enhanced evanescent Bessel fields may have important applications in optical manipulations of nanoparticles.
