Abstract: Array antennas with reconfigurable scattering fields are quite desirable for stealthy platforms to adapt a fast-changing electromagnetic (EM) environment. Here, we present an efficient ...

Abstract: We present an efficient higher-order spectral element method formulated in cylindrical coordinates for analyzing electromagnetic fields in anisotropic metamaterial fibers. The formulation ...

Neutron stars harbor some of the most extreme environments in the universe: their densities soar to several times those of ...

Earth's north magnetic pole is shifting and weakening. Ancient lava flows are guiding a better understanding of what generates and controls the Earth's magnetic field -- and what may drive it to ...

cuADMM solves multi-block SDP problems of the form: $$\min_X \left\langle C,X\right\rangle \quad\text{s.t.}\quad \begin{cases} \left\langle A_i,X\right\rangle = b_i, \quad i\in [m]\\\ X\in\Omega_+ ...

Zcash’s original creators have formally broken away from the Electric Coin Company (ECC) and launched a new independent development entity, marking the clearest structural split in the privacy coin’s ...
