Waveguide bends pose a problem for high-voltage ultra-wideband systems or for any transmission-line system with low-lossfast-risetime requirements, since only a straight section of conventional transmission line can support the pure transverse electromagnetic mode necessary to preserve the risetime of a transmitted pulse. We consider alternative concepts for compensation of waveguide bends. One concept, a graded dielectric strip line bend, is built and jested. By reducing the dispersion of a transmitted voltage step, this strip line bend demonstrates the principle of compensation of a waveguide bend by a graded dielectric lens.
