Abstract In this study we present a novel method to use a field collapse method together with fully automated near field scanning equipment to construct E- and H-field information of a system during transient ESD events. This inexpensive method provides an alternative way for system designers to validate and analyze the EMC/ESD capability of electronic systems without TLP pulsers, ESD simulators, or precision inductive current probes.

Near Field Scanning

An undergraduate experiment, of approximately six hours duration, is presented, in which the refractive index profile of a graded index fibre is measured using the near-field scanning method. The numerical aperture is obtained from far-field measurements and the core and cladding diameters are measured directly using an optical bench microscope and stage micrometer.
