 Workshop: Testing shielding theories 

Tuesday 
Transfer Function of Shielding Enclosures 
We will investigate the design versus performance characteristics of shielded enclosures: cables and boxes. Deriving and analyzing the transfer impedance, we will directly relate shield design to the electronic system EMC performance: emissions and immunity, crosstalk, biological safety. The effects of shield non-uniformities will be explained and quantified with regard to important wired and wireless electronic products. 

• From Microns to Miles and from Chips to Ships
• Using Transfer Impedance as the Shield’s Figure of Merit 
• Shield Design and Performance
• Solid Wall, Foil, Spiral, Braid, Mesh Shielding
• Multilayer Shields
• Shielding versus Crosstalk and Radiation
• UTP versus STP
• Shielding in Static, Induction, and Radiation Fields

•  Wireless and “Mobile” Product Shielding 

 Workshop: Designing an On-Board PCB Shielding 

Wednesday 
Expanding Shielding Understanding 
Building on case studies, we will establish the rationale for open parallel compensation shielding, explain its physical mechanisms, and 
develop design techniques for shielding: from chips to PCBs to test sites. The classical image theory and simulations will provide an elegant and persuasive illustration and convenient formulas to design such shielding, evaluate its performance and impairment effects.We will introduce the complete shielding classification, provide a comparison between the different shielding techniques, and generalize the shielding theory. 

• Ground/Power Planes and Lines/Traces as Shields
• Separation versus Parallel Shielding
• Open Parallel Shielding Rationale
• Method of Images and Current Returns 
• Shielding and Balancing
• Finite Size Planes, Edge Effects, Cuts, and Vias
• Shielding Classes, Paradigms, Topologies, and Dimensions
• Transfer Function of Parallel Shields
• Shield Effectiveness versus Shielding Effectiveness 

Optional Problem Workshop: Ground Plane Effect on Common and Differential Mode Emissions; Shield Reaction on Signal Transmission; Steel and Copper in Multilayer Shields – Not a Simple Problem 

Thursday 
Shielding System Engineering and Integration 
We will introduce system approach to cost effective and optimal shielding design based on-specific electrical, physical, mechanical, and economical factors with regard to selected design criteria. We start the discussion with shielding system grounding techniques and problems: single- and multiple-point grounding, ground loops, shield termination – connectors, gaskets, doors, windows, joints. We will formulate, implement, and illustrate by simulations and test results the rules of shielding system grounding, topology, and zoning. We will develop shielding design criteria and methods for boundary 
and optimal design, compare shielding with alternative EMI control techniques. At the Workshop, we will evaluate the dependence of a line radiation on the shield quality, grounding, and shielded circuit balance. 

• Shielding, Grounding, and All That Jazz
• System Approach to Electrical and Mechanical Shield Design
• Shielding Optimization 
•  Working with Shielding Impairments
• Shielding Performance Stability
• Issues and Control of Shielding Reaction on Transmission 

Friday 
Shielding Evaluation and Horizons 
We will address the shielding measurements, troubleshooting, testing, and test result interpretations. We will review the shielding standards, shielding system evaluation levels, measurement criteria, and logistics, and detail the shielding measurement triangle: test facilities, and test instrumentation, and test procedure. There are multiple test procedures and practices in use throughout the world, and their correct selection can make a difference between the product marketing success and failure. 

The course concludes with identifying shielding emerging applications, materials, technologies, and practices. Being more than 100 years old, shielding technology keeps accelerating, leading to amazing and important developments in EMC.
