【Abstract】 The principle of measurement of complex permittivity and permeability under microwave frequency using stripline method is introduced. The range and the error of measurement are discussed. The error of measuring ε r and μ r is within±5% with properly choosing sample length. The range method is suitable for measuring microwave absorption materials and non low loss ones.更多还原
