Fig. 13.1 Two modes of operation of a 2D plasmonic microscope. a Plasmon microscope operating
in the hyperlens mode: the plasmons generated by the sample located in the center of the hyperlens
propagate in the radial direction. The lateral distance between plasmonic rays grows with distance
along the radius. The images are viewed by a regular microscope. b Plasmon microscope operating
in the geometrical optics mode: nanohole array illuminated by external laser light acts as a source of
surface plasmons, which are emitted in all directions. Upon interaction with the sample positioned
near the focal point of the parabolically shaped dielectric droplet, and reflection off the droplet
edge, the plasmons form a magnified planar image of the sample. The image is viewed by a regular
microscope. The droplet edge acts as an efficient plasmon mirror because of total internal reflection
