the methods which are used to analyze microstrip antennas, are divited into three categories: empirical methods, semi-empirical methods and full-wave analysis. empirical and semi-empirical methods are generally based on some fundamental simplifying assumptions about quality of surface current distribution and substrate thickness. thses simplificatioms cause low accuracy in field evaluation. ful...

Abstract The population density of dwarf galaxies in low-density voids is likely determined by the dark matter halo mass function and how galaxy formation proceeds smaller halos. This depends on nature itself, making a tracer its properties. While dwarfs have been found smaller, closer voids, they proven difficult to find larger, more distant through magnitude-limited spectroscopic surveys. bec...
