From: Verification of the electromagnetic deep-penetration effect in the real world

Comparison between horn, LWA, and HTwLP penetrations averaged according to Eq. (14) in a lossy medium for which \(\upsigma =0.05\frac{\mathrm{S}}{\mathrm{m}}, {\upmu }_{\mathrm{r}}=1\mathrm{ and }{\upvarepsilon }_{\mathrm{r}}=1.\)
