摘要：
Three-layer slab waveguide with the substrate layer made of a left-handed material (LHM) of negative and complex permittivity (epsilon) and permeability (mu) is investigated as an optical sensor. The effect of the negative optical parameters of the substrate on the effective index, the power, the penetration depth, and the sensitivity of the senor is studied in details. The structure is also treated as an evanescent wave optical sensor.
