Abstract :
Measurements and modeling of plasmonic resonance positions as a function of orientation are presented in a manner that connects the common geometries with a formalism for all of momentum space. This framework is useful for understanding dispersion studied under an infrared microscope by rotating the sample about the optical axis of the microscope. Applications using the microscope for sensing and spectra of individual particles are presented.
