## How electromagnetic fields, current flow, and PCB design decisions drive real-world EMC performance

##### On-Demand

Electromagnetic compatibility (EMC) issues rarely begin at the test lab—they originate in the physics of how current flows, fields form, and circuits are constructed.

In this technical webinar, Astrodyne TDI Field Applications Engineer David Bourner walks through the physical origins of EMI, connecting electromagnetic theory directly to practical design decisions engineers make every day. From skin effect and reverse proximity effect to grounding strategies and PCB stackups, this session bridges theory and implementation.

### **What You’ll Learn**

Attendees will gain insight into:

- How electromagnetic fields manifest around conductors and current loops
- The relationship between voltage gradients, current flow, and EMI generation
- Skin effect and reverse proximity effect—and why frequency matters
- How large conductive loops lead to radiated emissions
- Star-point grounding and common EMI pitfalls
- Best-practice design strategies

### **Who Should Attend**

- Power electronics design engineers
- PCB and system architects
- EMC/EMI compliance engineers
- Hardware engineers working on industrial, medical, aerospace, or defense systems

### **Why Attend**

- Translate EMC theory into **actionable design guidance**
- Reduce late-stage compliance failures
- Improve first-pass EMC test success
- Learn directly from real-world field experience
