“…where E 0 is the wave field intensity emitted at the transmitting point, k ¼ 2Áπ λ is the wavenumber, ffiffiffiffiffiffi ffi s 0 sþs 0 q sets the geometric relationship necessary for the determination of L Di in an expression (21), and D ⊥ ΙΙ is the diffraction coefficient of the UTD method which is defined as follows [13]:…”

“…where R ⊥, ΙΙ n and R ⊥, ΙΙ 0 are the reflection coefficients of sides of diffraction edges at a given EM wave polarization, and a AE , β AE , L, and F Á ðÞ (Fresnel transition function) are expressed in the following expressions [13]:…”
