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 […]

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) […]

Mesh Sensitivity

Finite Element Mesh Variation as Quality Assurance in Space Charging EMA3D has tools which, when used in combination with Nascap-2K, provide the user a comprehensive and sophisticated space charging analysis framework.  One of the key capabilities that EMA3D provides is the ability to control the finite element mesh which serves as the basis for a […]

Space Applications

Advanced Electromagnetic Modeling for Space Applications Presentations a recent seminar and webinar can be found below. Today electromagnetic (EM) modelling plays an essential role in the development of challenging projects in every engineering field.  This is especially true for space applications, where performances and design specifications have recently experienced an incredible increase in complexity. This […]

Re-entry Antenna

Background and Motivation Space vehicles re-entering the Earth atmosphere  become shrouded by a “dense” plasma (bow shock wave). The plasma frequency exceeds 1 GHz in most of “cloud” around the vehicle. Link obstruction occurs in most directions, causing the “blackout” of the link to ground stations. The ESA Atmospheric Re-entry Demonstrator (ARD) program investigated experimentally the link […]
