Abstract

The main objective of this experiment is to get the power absorption coefficients (PAC) when the reflection coefficients, |SJ2 and transmission coefficients, |S2I| 2 is obtained from the reflection measurements and transmission measurements. Using transmission and return loss (reflection) measurements, we have developed a method for microwave nondestructive testing of several composite materials in the frequency range of 8 - 12 GHz (X-band). The key components of the measurement system are scalar network analyzer and horn antennas. The dielectric constants and the loss tangents for each samples are formerly known.
