Abstract: Determining the mainlobe region of an arbitrary pattern is a critical problem in the two-dimensional numerical pattern synthesis (2-D-NPS) method in which a number of artificial ...
Abstract: The 4-D antenna arrays with the irregular array topology have great advantages in simplifying the beamforming network and reducing the cost. However, the complexity of such synthesis ...
A new MEFP warhead with seven arc-cone liners which can form 7, 13 or 19 penetrators at different standoffs is designed. Dispersion patterns and penetration properties of MEFP are performed on five ...
Over 8,000 years ago, early farming communities in northern Mesopotamia were already thinking mathematically—long before numbers were written down. By closely studying Halafian pottery, researchers ...
