Abstract: A high effective refractive index structure may include one or more high effective refractive index materials disposed on a substrate. The high effective refractive index structure configured to respond to a light received at the high effective refractive index structure by at least generating one or more sub-diffraction limit illumination patterns for illuminating a specimen while one or more frames are captured of the illuminated specimen. The one or more sub-diffraction limit illumination patterns may include one or more speckle patterns. The one or more high effective refractive index materials may exhibit an effective refractive index equal to or greater than 3. Examples of high effective refractive index materials include hyperbolic metamaterial (HMM) multilayers, nanowire based hyperbolic metamaterials, and organic hyperbolic materials (OHM).
