Abstract
Electromagnetic coupling to cables has been a major source of EMC and EMI problems. In this paper, the methods of predicting the EM coupling and propagation in multiconductor transmission lines are presented. Crosstalk is an important aspect of the design of an electromagnetically compatible product. This essentially refers to the unintended electromagnetic coupling between wires and PCB lands that are in close proximity. Crosstalk is distinguished from antenna coupling in that it is a near field coupling problem. Crosstalk between wires in cables or between lands on PCBs concerns the intra-system interference performance of the product, that is, the source of the electromagnetic emission and the receptor of this emission are within the same system. With clock speeds and data transfer rates in digital computers steadily increasing, crosstalk between lands on PCBs is becoming a significant mechanism for interference in modern digital systems. To predict the crosstalk we designed a simple model of three conducting wires and took measurements for both nearend and farend crosstalk. Also the same model is being simulated by CST Microwave Studio (3D Electromagnetic Solver).
