Study on the reflection of EM wave from chiral material

We measured the reflection for six chiral samples with helix percentage of volume ranging from 0.4 to 6.4%. The normally incident wave is linearly polarized. Experiment results indicate that the heliex percentage of volume can be used as a sensitive parameter to control electromagnetic wave characteristics in chiral material. Discussion to experimental results is given. # 2003 Elsevier B.V. All rights reserved.
