Abstract: A wideband planar dipole array based on artificial magnetic conductor (AMC) surface is presented for phased array applications. One wideband in-phase hexagonal AMC cell is realized firstly.

Appropriately cut quartz crystals can be used as high-quality electromechanical resonators. Their piezoelectric properties (voltage across the crystal deforms it; deforming the crystal generates a ...

Faced with the problem of sub-synchronous oscillation (SSO) caused by the interaction between permanent magnetic synchronous generator (PMSG)-based wind farms and weak AC grids, we construct a ...

The dynamics of a robot may vary during operation due to both internal and external factors, such as non-ideal motor characteristics and unmodeled loads, which would lead to control performance ...

A large number of sparse signal reconstruction algorithms have been continuously proposed, but almost all greedy algorithms add a fixed number of indices to the support set in each iteration. Although ...

Conventional reconfigurable electrical and radio frequency (RF) structures commonly used in applications involving real-time reconfigurability in response to fast varying operational scenarios require ...

The decision letter from the journal was very supportive – it was clear our paper (Kirkegaard et al., 2016) would be published – but one of the referees definitely did not like the way we had combined ...
