In this paper, the radiated emissions generated by various split power/ground plane structures are studied. The magnetic field and electric field over the designed test pattern are simulated. Each of the results has different field pattern by bandwidth of signal frequency, gap space or gap location of the split ground gap. To reduce the radiated emission, the method for determining the gap space and...
In this study, we investigate the circular polarization-handedness inverter consisted of helical and zigzag films. The incident circular polarized light on this device becomes opposite circular polarized light with Bragg effect at output.
The irregular shape of Flexible Printed Circuit Boards (FPCBs) causes the EMI problem or unstable signal integrity that is the important factor to system performance. The FPCBs that is used the general mobile phone is modeled and simulated in this paper And it is analyzed about the EMI and signal integrity effects as the changes of the FPCBs?? position and shape. The structure of the FPCB consists...
