If you pull twice as hard on a spring, it stretches twice as far. However, when we introduce very large forces or complicated ...

Two-degree-of-freedom (2-dof) proportional-integral-derivative (PID) controllers are better than the 1-dof counterpart in the sense that the former can predominantly reduce large overshoot and ...

This letter propose a novel finite-difference frequency-domain (FDFD) algorithm for calculating band diagrams of photonic crystals composed of Debye-type dispersive materials. It will be shown that ...
