Five Reasons to Invest in Electromagnetic Simulation

Every engineer knows the feeling. The quiet pressure to get it right the first time. Deadlines are getting tighter, budgets leaner, and expectations higher. Whether you design satellite antennas, wearable medical devices, or a next-gen electric vehicle charger, the margin for error is vanishing. Electromagnetic (EM) simulation is not a luxury; it is a survival […]

Vampire Loads: The EMC Cost of Idle Electronics

The chills of spooky season linger well beyond Halloween. There is an ominous, but very real, phenomenon lurking in electronic systems: vampire loads. These silent power suckers drain energy when devices appear to be off and can haunt electromagnetic compatibility (EMC) efforts in ways you might not expect. Key Takeaways: What is a vampire load? […]

Lightning Protection for Wind Turbines: Risks, Solutions, and Simulation Insights

Wind turbines are a cornerstone of renewable energy, but their towering structures and remote locations make them highly vulnerable to lightning strikes. A single lightning strike can damage blades, nacelles, or control systems, leading to expensive retrofits and lost revenue. Without robust lightning protection systems, turbines face costly damage, extended downtime, and reduced reliability impacting energy output […]

Beginner’s Guide to EMI/EMC Simulation

As electronic devices become more complex and the market more competitive, the consequences of overlooking electromagnetic compatibility (EMC) and electromagnetic interference (EMI) reach far beyond the engineering team, they directly affect the customer. Devices plagued by EMI/EMC issues can suffer from unreliable performance, unexpected malfunctions, or even total failure during critical moments. This not only […]

Safeguarding Critical Rail, Power, and Data Center Infrastructure

The growing influence of artificial intelligence (AI) and cryptocurrency is driving a surge in the development of data centers throughout the United States. These centers will drive electricity consumption to record highs in 2025 and 2026. This raises a crucial question: how will electricity reach these data centers? Shared corridors with the railroad offer the […]

Speeding Up Large Platform Modeling and Simulation

EMA speeds up modeling and simulation of large platforms like never before. The finite-difference time-domain (FDTD) solver in Ansys EMC Plus and Ansys Charge Plus empowers users to solve bigger problems, delivering higher-quality products at lower costs in less time. EMA recently broke an internal recording by running a simulation on a model containing 1.6 […]

Efficient Lightning Transient Analysis

Electro Magnetic Applications, Inc. (EMA) is excited to share an exciting breakthrough: the successful completion of our first self-run lightning transient analysis (LTA) test. While this is not the first LTA test our staff has completed, this one stands out as a major milestone. It marks the debut of EMA’s new in-house equipment in action. […]
