The effect of shielding, grounding and bonding to the electromagnetic compatibility of high emission printed circuit board
Electromagnetic Compatibility (EMC) is the capability of the device or the system to perform its work correctly within its electromagnetic environment without causing the introduction of electromagnetic damage to that environment. Radiated Emission (RE) is one of the EMC tests that should be …

Crosstalk and Signal Integrity in Ring Resonator Based Optical Add/Drop Multiplexers for Wavelength-Division-Multiplexing Networks
… components leads to potential ‘Optical/Photonic’ electromagnetic compatibility (EMC) and signal integrity (SI) issues due to the close proximity of optical components and waveguides. Optical EMC issues are due to backscatter, crosstalk, stray light, and substrate modes. This thesis has focused on …
