With the enormously developing of the wireless communication technology, the electromagnetic environment exposing to the electrical devices is becoming more and more complex. Besides, the trends of designing high-speed digital computer systems are toward fast edge rates, high clock frequencies, and low voltage levels. The electromagnetic susceptibility (EMS) or immunity of the high-speed circuit has become an important issue today apparently. In this thesis, we will firstly establish the measurement environment and calibration technology for numerical validation. Then we employ the three-dimension finite-differential time-domain (3D-FDTD) numerical method compared to the finite element method (FEM) to simulate the EMS behavior of the power delivery network (PDN) and traces of the printed circuit boards (PCB). In addition to several types of layout of the traces studied in this thesis, we also explain the mechanism and phenomenon of the EMS of the power/ground planes of the PCB. Besides the EMS behavior research of the traditional solutions to suppress the power noise, we propose an electromagnetic bandgap structure (EBG) which has the broadband suppression of the power noise and is validated to be effective to improve the EMS problems. Finally, we also propose a novel concept to increase the signal integrity (SI) by shielding design.
