Jing Wang, Azriel Z. Genack
TL;DR
This paper demonstrates that transmitted microwave radiation can be decomposed into medium modes, revealing correlations and interference effects that explain wave diffusion and unify wave and particle descriptions.
Contribution
It introduces a method to decompose speckle patterns into modes, revealing modal correlations and interference effects in wave transmission through random media.
Findings
Modal field speckle patterns are strongly correlated.
Destructive interference between modes affects transmission.
The approach explains complexities in steady state and pulsed wave transmission.
Abstract
We show that the field speckle pattern of transmitted microwave radiation can be decomposed into a sum of patterns of the modes of the medium. We find strong correlation between modal field speckle patterns which leads to destructive interference between modes. This allows us to explain complexities of steady state and pulsed transmission of localized waves and to harmonize wave and particle descriptions of diffusion.
