Style of modest-scale gradient coils in magnetic resonance imaging by using the topology optimization strategyWith this paper, a generalized time fractional nonlinear foam drainage equation is investigated through the Lie group analysis system. According to the Riemann—Liouville derivative, the Lie place symmetries and symmetry reductions of the

An ultrathin micro-split Jerusalem-cross metasurface is proposed In this particular paper, which may efficiently transform the linear polarization of electromagnetic (EM) wave in the round polarization in ultra-wideband. By symmetrically employing two micro-splits around the horizontal arm (within the x path) on the Jerusalem-cross structure, the b
