Analysis on electromagnetic polarity of asymmetrical nanoshells

Some primary simulation results on the electromagnetic polarity of asymmetrical metal nanoshells are introduced. Influencing factors, including nanoparticle parameters such as ellipsoidal coronal thickness and incident field characters such as polarization direction, are studied. By optimizing the parameters, a nanoparticle with stronger electromagnetic polarity and higher energy absorptivity could be obtained, which provides a way to control its behavior. The cluster model consisting of asymmetrical metal nanoshells are also discussed.
