Webcurved waveguides · Scalar ﬁnite element method 1 Introduction Standard waveguide bends have a piecewise constant curvature proﬁle, which is due to the fact that a straight waveguide has zero curvature and a curved waveguide has a curvature, κ, that equals the inverse of the radius of the bend, 1/R. When a straight waveguide is joined WebA good design of a curved waveguide is intended to limit the pure radiation losses and the transition losses between the straight and the bent waveguides. Not properly designed bends may lead to the excitation of higher-order leaky modes in the plane of the bend. Accordingly waveguide bend and waveguide twist sections are manufactured
