Özet

We present computational analysis of nanoantenna arrays when they are used to detect and identify nearby nanoparticles. Solutions of frequency-domain scattering problems are performed by using a surface-integral-equation formulation that is suitable for composite structures involving metallic, dielectric, magnetic, and/or plasmonic objects. Acceleration is further achieved via the multilevel fast multipole algorithm that is developed for composite structures. Numerical results demonstrate the feasibility of particle detection and identification, even with sparse arrays with relatively large periodicities.
