FDTD 法を用いた3 次元建物モデルにおける電波侵入損失に関する数値的検討 Numerical Examination of Radio Wave Penetration Loss for Three-Dimensional Building Model Using FDTD Method 川畑, 侑生 カワバタ, ユウセイ 40191506 横田, 光広 ヨコタ, ミツヒロ Yokota, Mitsuhiro 横田 ヨコタ Yokota 光広 ミツヒロ Mitsuhiro 宮崎大学 University of Miyazaki Kawabata, Yusei penetration loss, FDTD method, Propagation loss, three-dimensional, building model In recent years, due to the exponential increase of mobile communication devices such as smartphones, the number of customers has increased and enormous data transmission / reception is carried out. As a result, it is pointed out that the frequency range gradually increase in future cellular mobile communications. As the frequency range increases, it becomes more susceptible to shielding buildings, the human body. Therefore, it is very important to know the radio wave fluctuation under various environments. Currently, various studies on building penetration losses have been conducted, but most of them are experiments by actual experiments and simulations using ray tracing method. In this study, we numerically calculate the propagation characteristics when various shielding objects are placed between transmitter and receiver using the FDTD method. We construct a three-dimensional building model and investigate the shadowing characteristics. Assuming various environments,the scattered power by objects is calculated for various conditions, and the influence of the penetration loss is considered. 宮崎大学工学部 Faculty of Engineering, University of Miyazaki 2018-07 jpn departmental bulletin paper VoR http://hdl.handle.net/10458/6421 https://miyazaki-u.repo.nii.ac.jp/records/5664 AA00732558 05404924 宮崎大学工学部紀要 Memoirs of Faculty of Engineering, University of Miyazaki 47 115 118 https://miyazaki-u.repo.nii.ac.jp/record/5664/files/p115-118_vol47.pdf application/pdf 1.4 MB 2020-06-21
