ABSTRACT

We studied the interfacial layer effects on the enhancement factor of local field and the optical induced bistability for small spherical metal/dielectric in linear host matrices. It is calculated the interfacial layer effect analytically and numerically on the enhancement factor of local field and the cubic equation of the optical induced bistability of the composite material. We have shown the parameters of the interfacial layer and calculated. We take positive, zero, and negative values which represents dielectric like, no interfacial, and metal like, respectively for the pure metal case. In the case of metal/dielectric for which we consider the interfacial layer particle the above mentioned properties are reversed so that it will be positive to realize the metal like properties of the interfacial layer. The analytical and numerical results show that the enhancement factor of local field is extremely enhanced and the optical induced bistability increased its domain.
