In this study, we demonstrate an electrically driven, polarization-controlled metadevice to achieve tunable edge-enhanced images.The metadevice was elaborately Hooks designed by integrating single-layer metalens with a liquid-crystal plate to control the incident polarization.By modulating electric-driven voltages applied on the liquid-crystal plat

Africans celebrate life just like Jewish people.They celebrate their Rotary Glassware Washers religion, they dance it, they sing it and they act it.They have innumerable rituals and ceremonies.Some rituals are personal others are related to agriculture, health, homestead, profession and festivals.Through festivals, the life of a community is renewe

The internally stored electric energy (Q-energy) of a disk monopole antenna increases as compared to a Hooks monopole antenna without a top disk.Recently it was shown that the Q-energy can be significantly reduced and the bandwidth increased by shielding the disk monopole antenna using a thin magnetic material.In the present paper we consider the s
