TY - JOUR T1 - Comparison on the Scattering Path Loss of Terahertz Waves in Fat Layer Under Air-Enclosed and Tissue-Enclosed Conditions TT - JF - ijop JO - ijop VL - 16 IS - 2 UR - http://ijop.ir/article-1-516-en.html Y1 - 2022 SP - 139 EP - 144 KW - Scattering Path Loss KW - Terahertz KW - Intra-Body Wireless Communications N2 - Using terahertz waves for intra-body communications between nanomachines is associated with dissipation during propagation, of which scattering is one of the most important effects. In this paper, scattering path loss with two different assumptions of air-enclosed and tissue-enclosed in subcutaneous fat is calculated and compared. The results show that for TM polarization, air-enclosed assumption gives smaller and greater scattering loss for frequencies less and bigger than 0.26 THz. The greatest difference between air-enclosed and tissue-enclosed results is observed for TE polarization at the approximate frequency of 0.4 THz. M3 10.52547/ijop.16.2.139 ER -
