Using time domain finite integration computation method and free space experimental method

systematically compare and analyze electric field polarization property of cross-shaped metamaterial absorber（ CSMA） and complementary CSMA（ CCSMA）

sensitivity with TE/TM mode oblique incident angles

and wave absorption mechanism. The wave absorptive intensity/reflectivity of both CSMA and CCSMA can be applied in senor design with TE mode incident angles. While for TM mode

harmonic peak of the CCSMA possess obvious red shift

which can be applied in design of frequency sensor/detector. After covered with sample to be tested on the top surface of wave absorber

resonant frequencies of both two models have red shift with increasing of permeability

and intensity of wave absorption of CSMA decreases linearly. The greater the thickness

the higher the sensitivity. CCSMA is dependent with permeability

remaining perfect absorption.
