TīmeklisThe core-mode cutoff plays a major role in evanescent field absorption based sensors. A method has been proposed to calculate the core-mode cutoff by solving the eigenvalue equations of a weakly guiding three layer optical waveguide graphically. The variation of normalized waveguide parameter (V) is also calculated with different … TīmeklisThe high signal-to-noise ratios achievable with evanescent field sensors are partially due to this relative insensitivity towards changes in the sample bulk. In addition, identical interactions at differing distances from the sensor surface will give rise to different signal shifts. Thus a receptor-ligand binding event (or indeed non-specific ... rick d taylor coroner
