MATERIAL MEASUREMENT APPARATUS

摘要

According to an embodiment of the present invention, a material characteristic measurement apparatus comprises: a first port including a first coaxial line section having a first outer conductor; a second port including a second coaxial line section having a second outer conductor; and a third coaxial line section which a first guide ring arranged between the first and second coaxial line sections, wherein a sample is fixed. The characteristic impedance of the third coaxial line section is different from the characteristic impedance of the first and second coaxial line sections. The first outer conductor, the second outer conductor, and the first guide ring may be made of a metallic material.
