The response can be controlled by means of an applied magnetic field through the optical Aharonov-Bohm effect and is ultimately required for the design of

The changes in ellipsometric parameters are 2 to 3 orders of magnitude above the detection limit of a modern ellipsometer. c EDP Sciences Article published by EDP Sciences and available at http://www.edpsciences.org/epl or http://dx.
