Effective graded-index guides for millimetre-wave applications

摘要: A novel dielectric waveguide that simulates optical graded index fibre is proposed for millimetre-wave applications. It shown a gradually varying refractive across the guide can result in well confined, single-mode propagation even several wavelengths wide. The desired profile achieved by thickness or height of waveguide. effective-dielectric-parameter concept introduced and used generating which approximated roof-top. Experimental results trial are presented discussed together with relative merits this guide.
