Unique Plasma Surrogates for
Coil + Matching Circuit at Full Power

Lossy medium:

Place lossy resistive film near inductively coupled sources
Place lossy dielectric + ground plane on capacitive structures

Very versatile:

Can test in field or at factory
Can test at full power
Can test non-intrusively on upper coils (chamber closed)

---

Usually series loss with adjustable reactance

Can simulate transients with parallel circuit of switch and alternate loss

Can simulate harmonics by parallel diodes

Cannot simulate the coil and the power radiating element

Several versions already made
