Abstract

This paper proposes a novel approach for estimating the utilization efficiency of metal particles to increase light energy absorption by a medium with a nonzero imaginary part of a medium refractive index. This method is implemented for spherical Ag and Au nanoparticles embedded in muscle tissue. Numerical calculations for spheres in absorbing media show that the utilization efficiency of metal particles increases with the decreasing absorbability of the medium.
