Study on wave absorption of finite thickness alternate layered lossy dielectric and lossy magnetic dielectric

Based on the common lossy dielectric and lossy magnetic dielectric, this paper attempts to approach the intrinsic impedance of air by alternating stacking. Taking E-M pattern and E-M-E pattern as examples, the effects of the number of cycles and the ratio of dielectric to magnetic thickness on the input impedance of laminated structures are studied. The calculation shows that in terms of eliminating reflection, this stacking method is much better than using lossy dielectric or lossy magnetic dielectric alone.
