Abstract
Based on the exact scalar wave equations of bent slab waveguides, locally leaky-mode attenuation constants for both TE and TM modes are derived by using the WKB tunneling theory. Changes in propagation constant due to waveguide bending are considered in our calculation. Under some assumptions, our results are found to be identical to other results obtained using entirely different methods.
