The broad bandwidth availability of sub-THz band enables the next generation of mobile systems. Because of the usage of the high-gain antennas, the communication link is highly directive and depends on the line-of-sight (LoS) channel. As one of the main challenges, the LoS channel can be easily shadowed. Due to the short wavelength, even a limb can obstruct the first Fresnel zone and can cause deep fading occasionally. When the obstacle has well-defined edges, the knife-edge diffraction (KED) and the uniform theory of diffraction (UTD) are useful. However, the shape of human body is complex and lacks well-defined edges. This paper aims to propose a channel model based on the windowed equivalent edge currents (EECs) defined by the modified edge representation (MER) for predicting the shadowing gain of the human body with the complex-shaped circumference of the cross-section (CCS).
