Advanced Photonics Research, EarlyView.An enhanced homogenization method for periodic lattices, applicable to any asymmetrical multipart structures, is proposed. This method simplifies intricate gratings into slab waveguides, predicts guided‐mode resonances and bound states in the continuum, without relying on numerical methods.

Trigonometric words ranking model for spam message classification
IET Networks, EarlyView., 2022 Abstract The significant increase in the volume of fake (spam) messages has led to an urgent need to develop and implement a robust anti‐spam method. Several of the current anti‐spam systems depend mainly on the word order of the message in determining the spam message, which results in the system's inability to predict the correct type of message when

Fault‐tolerant control technology of symmetrical six‐phase permanent magnet synchronous motor
IET Power Electronics, Volume 16, Issue 1, Page 37-52, 7 January 2023., 2023 Abstract In comparison with three‐phase motors, multiphase motors have garnered increasing attention owing to their high fault‐tolerant ability. When the motor has an open‐circuit fault, the stator combined magnetomotive force (MMF) changes, αβ and z1z2 subspaces are no longer decoupled, and the conventional vector control causes phase current ...

IET Renewable Power Generation, Volume 17, Issue 1, Page 18-35, 6 January 2023., 2023 Abstract An analytical model for transient stability assessment of hybrid AC–DC transmission systems is formulated, implemented, and validated. The equal‐area criterion, as known from the transient stability analysis of AC power systems, is redeveloped for AC–DC power systems using high‐voltage direct current (HVDC) transmission based on the voltage ...

An extensive critique on expert system control in solar photovoltaic dominated microgrids
IET Renewable Power Generation, EarlyView., 2023 Solar and wind power have recently become a potential option in power systems and act significantly to meet load penetration demands. The present growth of such renewable energy sources has shown an exponential increase. The high penetration of such systems helps a grid effectively meet its load in an irregular demand but also creates some disturbances
