Abstract :
The effect of lift-off (i.e., air-gap) error in dual waveguide probe material characterization measurements is presented here. The mitigation of this error using a two-layer dyadic Green´s function analysis is also discussed. Experimental results for gap scenarios of an electromagnetic shielding material are presented for validation purposes.
