In this paper, a method of transmission phase-shift is proposed to determine complex permittivity of biological sample which is performed using a WR90 type X-band rectangular waveguide. Some samples of chicken meat, liver, and skin are applied as biological materials for the experimentation. The irregular shape of biological sample is examined by placing it into a thin container to obtain a flat surface and putting the container in inside of the rectangular waveguide. The complex relative permittivity of each sample is extracted from measured S-parameters and then determined using the method. The results show that the method could successfully determine the complex permittivity of biological sample. In addition, the water content in the material has become a critical issue to be considered in the examination especially for the biological sample with high permittivity.[/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]Biological samples,Biomedical research,Complex permittivity,Complex permittivity determination,Complex relative permittivity,High permittivity,Irregular shape,Transmission phase[/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]Biological sample,Complex permittivity,Transmission phase-shift,X-band rectangular waveguide[/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 partially supported by the program of Researches, Community Services, and Innovation (Program Penelitian, Pengabdian kepada Masyarakat dan Inovasi, P3MI), Institut Teknologi Bandung, Indonesia, FY2020.[/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/TENCON50793.2020.9293836[/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]
