4. ES45 – Who are we?
• Telemetry
• Electromagnetic Environmental Effects
(E3)
• Lightning, Solar Flares, ESD, HIRF, EMP
• Supporting ISS and SLS
• Interference testing

5. What is Electromagnetic Compatibility?
• A branch of electrical engineering concerned with
mitigating the unwanted generation, propagation, or
reception of electromagnetic signals and effects
• Helps to prevent electromagnetic interference (EMI) as
well as possible damage to operational equipment

6. Parallel Wire Coupling
• Coupling refers to the transfer of energy
between circuit mediums
• ‘Crosstalk’ specifically refers to capacitive
and inductive coupling (due to electric and
magnetic fields)
• Want to be able to predict voltages on one
wire due to nearby voltage-induced wires
• Attempting to validate a Boeing Matlab
model

9. What We Found
• Coupling measurements much higher than
those predicted by the model
• Most of the coupling was inductive
• Proper shielding procedures cannot be
neglected

10. Other Projects
• NSI Fuse Testing
• Antenna Design
• Power Supply Controller Soldering
