Cellulose Microfibril Angle in the Cell Wall of Wood Fibres

Biological Reviews, 2004
ABSTRACT The term microfibril angle (MFA) in wood science refers to the angle between the direction of the helical windings of cellulose microfibrils in the secondary cell wall of fibres and tracheids and the long axis of cell. Technologically, it is usually applied to the orientation of cellulose microfibrils in the S2 layer that ...

Refraction Angle Approximation Algorithm for Wall Compensation in TWRI

IEEE Geoscience and Remote Sensing Letters, 2016
Wall penetration of the electromagnetic wave causes target image defocused and displaced from its true position in through-wall radar imaging. To solve this problem, this letter proposes an approximate wall compensation algorithm, named the refraction angle approximation algorithm, which assumes that the actual refraction angle is approximately equal ...
