As proposed by Herminghaus,a hierarchical structure could render any surface nonwettable as long as the roughness amplitude at small scales is sufficient to sus
By means of the transfer-matrix method, the effects of parameter modulation on the quality of near-field imaging in one-dimensional photonic crystal consisting
Using temperature distribution as an exteal parameter to change symmetry and measuring frequency spectrum of acoustic resonances in aluminium blocks, we investi
We apply the effective-medium theory to a multi-component mixture system, by which the effective longitudinal and Hall conductivities can be calculated.We find
