RESUMO
We propose a novel semi-analytic design strategy for dielectric one-dimensional multilayer biosensors that is based on a relation between the angular sensitivity and the optical power flow of the Bloch surface wave guided by the multilayer. We show that our strategy can be used to optimize both the sensor's sensitivity and figure-of-merit without the need for extensive numerical parameter sweeps.

We present the design of a supporting photonic crystal structure that would allow for the excitation of the predicted transverse electric (TE) polarized excitation in a single layer of graphene. We show that it is possible to measure this excitation at room temperature, and that adding an extra layer of dielectric material on top of the structure would further facilitate the experimental observation of the graphene mode.
