Abstract: An image sensor includes a group of sensor units, a color filter layer disposed within the group of sensor units, and a dielectric structure and a metasurface disposed corresponding to the color filter layer. The metasurface includes a plurality of peripheral nanoposts located at corners of the group of sensor units from top view, respectively, a central nanopost enclosed by the plurality of peripheral nanoposts, and a filling material laterally surrounding the plurality of peripheral nanoposts and the central nanopost. The central nanopost is offset from a center point of the group of sensor units by a distance from top view.

Abstract: The present invention relates to a method for comparison of multiple tropical cyclone routes. The method is implementable through a mobile device having an application processor and a touch-sensed display. The method is capable of determining multiple reference cyclone routes relevant to an concerned cyclone route by comparing each of multiple historical cyclone routes, each of which routes consists of multiple cyclone center coordinates, with an estimated cyclone route consisting of multiple estimated cyclone center coordinates for representing the concerned cyclone route.
