To improve the impedance matching condition and broaden effective absorbing bandwidth, a series of cylindrical periodic structured gypsum composites with different kinds carbonaceous materials as absorbents were fabricated by two-step molding process. The influences mass fraction helical carbon fiber (HCF), nanotube (CNT), graphene (GE) on morphology, permittivity, resistivity, electromagnetic ...

The development and optimization of structured materials, such as tissue paper benefit from modeling strategies that take into consideration its structural hierarchy at the fiber levels. use an innovative three-dimensional voxel approach to model both 3D structure were validated by comparison computational structures with laboratory-made structures. main goal this work was obtain a implementati...
