Internal Charging

Topic: EMA3D-Internal: A Comprehensive Platform for 3D Internal Space Charging Abstract: In this webinar, we present the newly developed fully 3D internal space charging software tool: EMA3D-Internal.  Spacecraft charging is a well-known problem for space vehicles.  Advanced evaluation of spacecraft charging threats to a particular mission can inform design and drastically reduce the risk for […]

E3 Tools

Webinar: Dealing with cables, cavities and platform antennas in a PRACTICAL way Presented by: Dr. Tim McDonald Abstract: EMC and E3 engineers have real challenges in dealing with cables, cavities and platform antennas in real electronics equipment, aircraft and vehicles. It is reasonably easy to solve for a perfect cable illuminated by a perfect plane […]

Surface Discharges

Using EMA3D to Calculate Surface to Surface Discharge Transients When a space vehicle undergoes surface charging in a space plasma environment, there is the potential for discharges and arcing to occur.  These discharges may cause damage to surfaces or may couple electromagnetic energy to antennas and cables.  In this blog entry we discuss how to […]

OCT Method

Oversized Cavity Theory for RE/RS Assessment up to 40GHz The Oversized Cavity Theory (OCT) is a numerical technique for aerospace systems including aircraft and communication satellites radiated emissions and susceptibility (RE/RS) assessment. The method is based on a power-balance approach, i.e. on the premise that, with statistical fields present in an electrically large cavity, the […]

Surface Charging

Surface Charging Simulations of an Orion-like Spacecraft in a Geo Space Plasma Abstract: Surface charging in a space plasma environment is a critical safety issue for many space vehicles. This is particularly true for vehicles that spend time in geosynchronous altitudes. We present results on surface charging for an Orion-like spacecraft in a geosynchronous plasma […]


Farnborough International Airshow 2016 11th – 15th July, Farnborough UK. This year EMA will be attending the Farnborough International Airshow, one of the world’s premier airshows. Along with our European partners Ingegneria Dei Sistemi, we will be showcasing our electromagnetic modeling and simulation tools for the aircraft and satellite industries, as well as one of our UAV’s […]

Plasma Discharge

Topic: Space Plasma Discharge Transients from EMA3D Presenter: Bryon Neufeld Abstract: We demonstrate EMA3D’s ability to predict discharge transients from surface charging in a space plasma.  In our analysis, we obtain surface charging results in a space plasma environment and then evaluate discharge transients to cables and antennas.  We consider spacecraft-to-plasma, surface-to-surface, and spacecraft-to-spacecraft (rendezvous) […]
