Abstract:
Super-oscillating functions are band-limited functions that oscillate locally faster than their higher Fourier component. These functions were studied in the past for super-directive antennas as well as for imaging and microscopy. Here I will present new applications of super-oscillations for trapping and manipulation of nano-particles, for generation of electron beams with sub-diffraction central spot, for realization of nonlinear frequency converters with arbitrary narrow spectral and thermal bandwidth, and finally for structured illumination microscopy.
