The irregular shape of biological tissue as a specimen is overcome by placing it into a thin container to obtain a flat surface and then put it in inside of the waveguide. The dielectric property focused in this work is complex relative permittivity which is extracted from S-parameters and analyzed using transmission phase-shift (TPS) method. To verify the proposed method, several widely known materials are measured and compared with the Nicholson-Ross-Weir (NRW) method. In addition, it is demonstrated that the thickness of sample has a critical point to be considered in measuring a specimen with high relative 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]Analytical approach,Biological tissues,Complex relative permittivity,Nicholson ross weirs,Property measurement,Relative permittivity,Transmission phase,X-band waveguides[/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][/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 sponsored by Institut Teknologi Bandung Research Grant 2018 under the contract number 7526/I1.B04/PL/2017.[/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/PIERS-Fall48861.2019.9021622[/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]
