SUMMARY
The discussion focuses on calculating the dB loss for a 3GHz electromagnetic (EM) wave traveling through a medium with a permittivity of ϵ=1.5ϵ_0 and a loss tangent of 9E-4 over a distance of 2 meters. The initial attempt at a solution yielded an incorrect value of approximately 6*10^6 dB loss. Participants emphasized the relationship between wave number (k) and frequency, noting that EM loss is proportional to k. The loss tangent was identified as a critical factor in determining the dB loss.
