We demonstrate a 7-bit photonic true-time-delay (TTD) system which uses an 8×8 micro-optical-electromechanical system (MOEMS) optical switch for phased array a
The activity of MgO in MgO-B2O_3 melt was experimentally determined at 1773 and 1823 Kby means of slag-liquid Sn equilibrium.The activity of B_2O_3 was calcula
