Wavelength Independent Optical Microscopy and Lithography
Abstract
At the start of the present contract we had only a rudimentary understanding of the nature of the near-field. As a result of this contract, great progress has been made both in building a theoretical foundation and underpinning this foundation with crucial experiments. The fundamental principle underlying the NSOM concept is outlined in Figure 1, where visible light is depicted as being normally incident on a conducting screen containing a small (sub-wavelength) aperture. Because the screen is completely opaque, the radiation emanating through the aperture and into the region beyond the screen is first collimated to the aperture size rather than to the wavelength of the radiation employed.
