Plane wave scattering on Janus spheres — •Jochen Wauer1 and Tom Rother2 — 1Hochschule Neubrandenburg, University of Applied Sciences — 2German Aerospace Center(DLR), Remote Sensing Technology Inst., Neustrelitz
Janus spheres are objects of growing interest in different fields of technology. They can be used in medicine for a precise drug positioning, and they hold an enormous potential for the development of new and active materials, just to mention only two applications of recent interest in nanotechnologies. Some of those Janus spheres are still industrially manufactured. It must be noted, however, that there exists a certain lack of knowledge about the scattering behavior of such objects although it might be of some interest not only for diagnostic purposes but also for discovering new applications. We present the application of the T-matrix method to solve the scattering problem of a plane electromagnetic wave on a dielectric sphere the surface of which is partially covered with a perfect metal. Additionally, the scalar scattering problem, i. e. the scattering of acoustic waves on different types of Janus spheres will be discussed. First results are presented, and an interesting effect for specially oriented Janus spheres at lower size parameters is discussed.
