Modeling Cables

Webinar: Modeling Complex Cable Harnesses in EMA3D® Simulations Computation Electromagnetic (CEM) simulations play an ever increasing role in the analysis and support for aircraft and aerospace programs. CEM can be used to evaluate electromagnetic environmental effects as well as EMC/EMI system problems for design and certification support. This analysis not only can be used early […]

2017 DoD E3

DoD E3 Program Review 2017 EMA and IDS would like to invite you to join us at the Department of Defense Electromagnetic Environmental Effects Program Review (DoD E3 Program Review 2017). We will be consolidating the EMA and IDS partnership and showcasing our combined capabilities that that cover critical tasks in E3 analysis and spectrum […]

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 […]

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 […]

Charging Webinar

Topic: Advanced CAE Tools for Spacecraft Charging Analysis with NASCAP-2K Presenter: Bryon Neufeld Abstract: EMA3D® includes advanced CAE tools for spacecraft charging analysis with NASCAP-2K. These tools allow the user to import native CAD (in almost any format) directly into the EMA3D platform to serve as the basis for their surface charging simulation, ensuring a […]

Spacecraft Charging

Spacecraft Charging EMA3D® includes advanced CAE tools to extend NASCAP-2K and provide spacecraft charging analysis for plasma interaction and EMC characterization in space. Many US companies rely on NASCAP-2K, but find the CAD and CAE tools, such as meshes, to be cumbersome and underdeveloped. EMA3D gives the ability to simplify, modify, and defeature geometry to […]
