The Power Electronics Research Group at KU Leuven / EnergyVille (Genk, Belgium) tested Denka® plates with an Agilent 4294A precision impedance analyzer across 1–30 MHz.
Findings
- Frequency-dependent high-frequency voltage attenuation across the band
- Peak attenuation of 13–15% per plate (≈ 1.2–1.4 dB) at 25–30 MHz
