| Abstract: | The transfer matrix method（TMM） is used for the nano-metal-dielectric multilayer films.The characteristics of local field enhancement and optical transmission are studied.It＇s shown that when the wave vector matching condition is satisfied,the bulk plasmon polariton（BPP） will be excitations in metal-dielectric-metal（MDM）structure,and the number of BPP-modes is equal to the number of the dielectric layer.When the BPP-mode is excited,the incident light and free electrons in the metal layer will couple.This drive the incident light to transmit through the metal layer and to the transmission for the maximum while the local field intensity inside the medium significantly enhanced. |
| Keywords: | Bulk plasmon polariton transfer matrix method local field intensity transmission |
