be characteristic of 基本解釋
18. The used microstrip interconnects have the following characteristics: various characteristic impedance, length, dielectric thickness and relative dielectric permittivity. The used other kinds of transmission lines are chosen to achieve the comparison: grounded co-planar waveguides, striplines, coated-microstriplines. The analysis is mainly based on experiment measures which incorporated 3D full-wave EM simulation in frequency and time domain. Then the differential microstrip line and stripline will be analyzed on signal integrity by used mixed-mode S-parameters based on 3D EM simulation in frequency domain.3. Various discontinuities in high-speed interconnects will be analyzed on signal integrity.
