Multifrequency superscattering is a phenomenon in which the scattering cross section from a subwavelength object simultaneously exceeds the single-channel limit at multiple frequency regimes. Here, we achieve simultaneously, within a graphene-coated subwa
We investigate the spectral approaches to the problem of point pattern matching, and present a spectral feature descriptors based on partial least square (PLS). Given keypoints of two images, we define the position similarity matrices respectively, and ex
A novel near-infrared light responsive microcapsule system, gold nanorod-covered DOX-loaded hollow CaCO3 microcapsule (AuNR-HM-DOX) is developed for cancer therapy. The hollow CaCO3 microcapsules were prepared based on the self-assem
We project a compact T-branch beam splitter with a micron scale using a two-dimensional (2D) photonic crystal (PC). For TE polarization, one light beam can be split into two sub-beams along opposite directions. The propagating directions of the two splitt
