We compare and contrast concave and convex lenses by drawing ray diagrams. In this Closer Look segment on Lenses, we compare and contrast concave and convex lenses by drawing ray diagrams and ...

Dielectric lens antennas are attracting the attention of researchers for applications at higher frequencies due to their high radiation capability, low side lobe levels, and simple structure. This ...
