Crosstalk reduction between metal-strips with subwavelength periodically corrugated structure

摘要: A new kind of microstrip line on which the spoof surface plasmon polaritons (SPPs) can propagate at low frequencies (such as microwave or terahertz regime) is developed. The upper metal-strip designed by introducing subwavelength periodically inward openings edges. Numerical methods are used to analyse dispersion relation and asymptotic frequency. It verified that such structured lines support SPPs in frequency range between 200 MHz 8 GHz. Compared with quasi-TEM modes conventional lines, be highly localised so crosstalk different very weak. Therefore this would great use high density circuits high-speed systems.
