Abstract: Errors analysis of quasi optical open cavity, which is used to measure the complex dielectric constant of the dielectric plate accurately, is presented. The errors from the approximating theory and the errors due to the measurement system and measurement process are described. The formulas are deduced, and the simulation results and measurement results are presented.

Key words: Millimeter waves, Quasi optical open cavity, Errors analysis
