A dual-band coaxial waveguide mode converter is investigated.In the converter, the TEM mode (Coa.TEM) and TMol circular waveguide (Cir.TM) mode are transformed
We investigate epitaxy of AlN layers on sapphire substrates by molecular beam epitaxy.It is found that an atomically fiat surface can be obtained under Al-rich
A simple particle hopping model is proposed to investigate the interaction of two groups of pedestrians,namely straight walking pedestrians and cross-pedestrian
