Taking the symmetric slab wa¨eguide as an example, we show that radiation modes of a weakly guiding planar optical wa¨eguide can be approximated by the free-space modes; their field expressions and normalization constants are simple and physically understandable, and can be obtained directly without

## Abstract The guidance conditions of TE and TM waves with both real and imaginary transverse wave numbers in a grounded slab waveguide of uniaxially anisotropic leftβhanded material are derived. The mode properties for guided TE waves, such as the existence of guided modes, the number of possible
