Surface-wave elimination in integrated circuit structures with artificial periodic materials

Surface-wave (or dielectric slab) modes in integrated circuit structures often result in undesired energy losses and cross-talk between components. In this paper surface wave elimination in integrated circuit structures by using planar artificial periodic substrates is investigated. A full-wave three-dimensional integral-equation moment-method is used to find the propagation constants of guided-wave modes on grounded dielectric slabs with planar periodic implants. The cases of rectangular blocks in both a rectangular lattice and a triangular lattice are investigated The limitation on complete (omnidirectional) surface-wave elimination with material grating is discussed This work may lead to the development of many novel integrated circuit components with potential significance in millimeter waves and optics.
