Abstract
Cylindrical surface waveguides are extremely useful for transporting a surface wave in one dimension with low attenuation when the medium surrounding the surface waveguide has low attenuation. Additionally, surface waveguides guide a pure low-order mode with no cutoff frequency and low distortion, while higher-order modes are quickly attenuated. In this work, we develop simulations and conduct experiments to design a large-radius surface waveguide which can be measured with existing lab equipment. Additionally, we develop and examine the effects of small, simply-shaped couplers, which are highly inefficient at launching surface waves. We also measure the effects of bends on a large-radius surface waveguide (approximately 24% of a wavelength). We study the propagation of the surface wave with a surrounding medium of air and of sand, which is a lossy medium.
