In the analysis, a point-matching method is combined with Muller\u0027s method and is applied to determine the propagation constant of the dominant mode. We compare the calculated result with previous experimental data, as well as that of the experimental equation and the theoretical result of a circular waveguide having the same cross-sectional area. Finally, an approximate equation for the attenuation constant is derived from the point-matching solution so that one can determine or estimate the value without elaborate calculations.", "subitem_description_type": "Abstract"}]}, "item_5_full_name_3": {"attribute_name": "\u8457\u8005\u5225\u540d", "attribute_value_mlt": [{"nameIdentifiers": [{"nameIdentifier": "19", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Yamaguchi, Yoshio"}, {"name": "\u5c71\u53e3, \u82b3\u96c4"}]}]}, "item_5_publisher_7": {"attribute_name": "\u51fa\u7248\u8005", "attribute_value_mlt": [{"subitem_publisher": "IEEE"}]}, "item_5_rights_15": {"attribute_name": "\u6a29\u5229", "attribute_value_mlt": [{"subitem_rights": "\u00a9(1985) IEEE.
