SUMMARY:Characterization of Electromagnetic Hot Spots Using Apertureless Ne
	ar-field Scanning Optical Microscopy
DESCRIPTION:Featuring Marc McGuigan\n\nPart of the Departmental Seminars.\n
	\nDissertation Committee:\nBennett Goldberg\, Anna Swan\, Syam Erramilli\, 
	David Campbell\, James Rohlf\n\nAn understanding of nanoscale light-matter 
	interactions is a prerequisite for the development of active photonic and p
	lasmonic elements. These nanoscale interactions are difficult to study with
	 conventional microscopy tools because most far-field microscopes cannot re
	solve features smaller than the diffraction limit (half the wavelength of t
	he illuminating light). Near-field microscopes allow for the control and ch
	aracterization of nanoscale light-matter interactions with sub-diffraction 
	limit spatial resolution.  This talk will describe the process of building 
	an apertureless near-field microscope to characterize electromagnetic hot s
	pots on aluminum nanostructures.  I will also discuss a novel polarization-
	based technique that should help us contrast nanoscale electromagnetic enha
	ncements from a far-field\, diffraction-limited background. \n\n\n![Marc Mc
