Abstract
It is shown theoretically that the field shift Δx and phase constant change Δβ in twodimensional threelayered dielectric or hollow waveguides bent uniformly with large bending radiusR are related by Δx = 2RΔβ/β 0 whereβ 0 is the axial phase constant The relationship predicts that the field distributions of the TE0 or TM0 mode shift toward the outward direction of bending whereas those of other TE n or TM n n=12 modes shift inward in a hollow waveguide Characteristic features in dielectric waveguides are also described
