The method has been implemented to analyze and solve a wide variety of electromagnetics (EM) problems. The rectangular waveguide with the cross-section of 40\mathbf{mm}\times 20\mathbf{m} and loaded with anisotropic dielectric material is modeled as numerical expression of magnetic and electric fields in which the interaction of fields are analyzed using 3D-FDTD method. The results of analysis in terms of EM wave and mode that appear in the waveguide are then validated theoretically. Furthermore, similar analyses using 3D-FDTD method are also applied for an hollow rectangular waveguide as well as for a rectangular waveguide which is loaded with isotropic dielectric material. The analysis results demonstrate good agreements with the theoretical predictions, although there were 0.26-2.32% discrepancies occurred in the 3D-FDTD method.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]3D FDTD,Anisotropic dielectrics,Electromagnetics,Magnetic and electric fields,Similar analysis,Three dimensions[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]3D-FDTD method,anisotropic dielectric material,rectangular waveguide,resonant frequency[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text]This work is supported in partial by the program of postgraduate team research (Penelitian Tim Pasca Sarjana) FY2017-FY2018 from the Ministry of Research, Technology and Higher Education, the Republic of Indonesia.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.1109/ICWT.2018.8527835[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
