Abstract:
A plane wave is incident normally from vacuum (ƞΟ = 1) onto a smooth surface. The substrate has three layers; the top most layer has thickness ɗ1 and permittivity ϵ1. The corresponding numbers for the next layer are ɗ2; ϵ2, while the third layer which is semi-in nite has index ɳ3. The Hallikainen model [1] is used to relate volumetric soil moisture to the permittivity. Here, we consider the relation for the real part of the permittivity for a typical loam soil: ɛʹ(mv) = 2:8571 + 3:9678 * mv + 118:85 * mv2
