Abstract
C-apertures enable a 1000x improvement of power throughput compared to square and round sub-wavelength apertures, while maintaining a near-field spot size of < l/20. We will discuss the underlying physical principles that give rise to this improved performance using topological visualization methods. Knowledge thus gained is used to develop new sensors and applications in bio-sensing, optical data storage, and magnetic storage. We will describe some of our latest results and indicate potentially fertile areas of research where C-apertures may be employed to enable new applications.
