Biomolecules and nanostructures

The Optical Sciences group studies the interaction of light and matter. Our current focus is on detection and sensing/imaging with an emphasis on the development of integrated photonics. We are part of Twente University's Department of Science and Technology and member of the MESA+ institute.

    Description

    Standard diffraction theory says that fields can only be focused down to a focus-size comparable to the free-space wavelength of the field. However that theory is based on a number of approximations. Since the Maxwell equations can be inverted in time it is clear that fields can be focused back to the size of an emitter which can be far sub-wavelength. In this project we will design an antenna that inverts the dipole radiation pattern to generate a field that focuses to a spot (sub-mm) that is much smaller than the wavelength (several meters).
