报告摘要：In this talk, we will present the enhancement for the electric and magnetic fields in a two-dimensional subwavelength rectangular cavity. We show that the significant field enhancement may be achieved in both non-resonant and resonant regimes. The proofs are based on variational approaches, layer potential techniques, boundary integral equations, and asymptotic analysis. Numerical experiments are also presented to confirm the theoretical finding.
