- We show that the spatial structure of electromagnetic vacuum fluctuations, predicted by quantum electrodynamics, can be indirectly observed using thermal noise at radio frequencies. Using simple lab equipment like coaxial cables and RF splitters, we detect a clear suppression of thermal noise near conducting boundaries, mirroring the expected modulation of vacuum modes. This provides accessible, experimental evidence for quantum vacuum behavior without requiring advanced optics or cryogenics.
