At first, a loss tangent tan δ of the sapphire rod and R_s of the HTS films are evaluated separately from the results measured for the TE_<021> and TE_<012 >modes with close resonant frequencies. Secondly, R_s values at two different resonant frequencies for the TE_<011> and TE_<022> modes are measured using a well-known relation for sapphire tan δ/f = constant, where f is a frequency. R_s values of HoBa_2Cu_3O_<7-x> thin films were measured in the frequency range of 10 to 43 GHz by using four sapphire rod resonators with different sizes. As a result, it is found that these measured results of R_s have a characteristic of frequency square., copyright(c)2003 IEICE 許諾番号:07RB0174  http://www.ieice.org/jpn/trans_online/index.html, text, application/pdf}, pages = {1721--1728}, title = {Frequency Dependence Measurements of Surface Resistance of Superconductors Using Four Modes in a Sapphire Rod Resonator(Special Issue on Microwave and Millimeter Wave Technology)}, volume = {E86-C}, year = {2003}, yomi = {ハシモト, トオル and コバヤシ, ヨシオ} }
