  7. Abstract:
  8. This thesis explores the feasibility of implementing terahertz wireless communication in indoor environments (as suggested in 6G) by modeling the propagation of terahertz band waves. The roughness of indoor surfaces at the terahertz frequencies is investigated through the detailed examination of the electromagnetic fields scattered from these surfaces using the method of moments (MoM). To account for the random roughness of these surfaces, the Monte Carlo method is utilized, generating surfaces with Gaussian statistical distribution, and obtaining the scattered electromagnetic fields using MoM. The final results represent an average of all simulated scenarios. In addition, the study considers using a resistive sheet to avoid virtual reflection phenomena We modeled the wireless channel using the ray tracing method. We used MATLAB software to simulate and evaluate the propagation of terahertz waves in a common indoor scenario. We examined the wireless communication status of terahertz waves in shadow regions and confined areas with conventional separators. Using TE and TM polarizations, we found that TM polarization and surface roughness were unsuitable for reception in shadow regions. Using glass separators instead of PVC separators resulted in a decrease in path loss
