ABSTRACT
A method for obtaining the complex permittivity of a Maxwell Garnett liquid with the aid of spectral surface plasmon resonance spectroscopy is presented. The Maxwell Garnett liquid is assumed to consist of small absorbing spherical inclusions in a host liquid. It is shown that the permittivity of the inclusions can be calculated if the optical constants of the host liquid are known. It is believed that such a method will gain increasing importance in the analysis of biological reactions.

    Transmission metallic gratings having the shape of converging-diverging channel (CDC) give an extra degree of freedom to exhibit enhanced transmission resonances. By varying the gap size at the throat of CDC, the spectral locations of the transmission resonance bands can be shifted close to each...
