EMI from a Slot in a Box

By Cody Weber and Bryon Neufeld Benchmark Simulation Using EMA3D It is important to demonstrate that EM simulation packages can reproduce measured data for problems of interest. EMI from a slot is a common EMC concern. This demonstration compares an EMA3D simulation to an existing measurement in the literature. The electromagnetic interference (EMI) from a […]

Lightning Initial Attachment for Zoning

By Jennifer Kitaygorsky This post describes the steps to perform lightning initial attachment for zoning. Lightning zoning for aircraft involves separating each aircraft outer surface area into a specific category based on its likelihood for lightning attachment, lightning sweep and lightning hang-on. The steps required are detailed s in SAE ARP 5414A: Aircraft Zoning. The task is divided into […]

Radiated Susceptibility Analysis

By Cody Weber Radiated susceptibility analysis for electronics and avionics is an important aspect of electromagnetic environmental effects (E3) and electromagnetic compatibility (EMC) efforts. The work involves: Determining the environment or radiating emitter field levels. The source of emission may be external to the aircraft (HIRF/EMR) or from another known emitter on the platform. Analysis […]
