Abstract :
A new type of microwave structure is investigated. The structure can be fabricated using printed-circuit techniques; it has slow-wave characteristics similar to those of a helix; it also exhibits leaky-wave characteristics. The characteristic equations for the different modes of the structure are derived and the dispersion characteristics calculated. Results show the slow-wave nature of the structure, the effects of variation in the physical parameters, and the leaky-wave characteristics. Preliminary measurement results, supporting the leaky-wave characteristics, are also presented. The structure is expected to have potential applications in guided-wave, radiating, and electron-beam devices.
