Fig. 3. Fraction of electromagnetic power transported by the transverse-magnetic mode along a single-rod probe (SRP) within a cylinder of radius r, coaxial to the SRP. Radius of SRP r_SRP = 0.005 m. In all cases ${sigma}$ _SRP = 5.8 x 10⁷ S m^–1 and µ_r = 1.0. Top: SRP in air, ${epsilon}$ _r = 1; middle: SRP in dry sand, ${epsilon}$ _r = 2.8; bottom: SRP in wet sand, ${epsilon}$ _r = 20.
