Heterogeneous two-dimensional layers have been the subjects of many ellipsometric studies. An unambiguous characterization of especially metal heterogeneous layers is not straightforward. Adsorption of Au nanocolloids leads to a well-defined heterogeneous layer, although the analysis of ellipsometric spectra is not simple. Standard effective medium theories are shown not to be capable of a correct...
An attempt has been made to model the acoustic pressure field and the spatial distribution of the cavitation phenomena in a dual frequency sonic processor. A methodology has been presented with numerical simulations to optimize the conditions of the dual frequency acoustic field. The simulations presented in this work reveal that with manipulation of the parameters (viz., frequency ratio and the pressure...
