Abstract: This paper presents a wide-angle beam-scanning 3D compound Gradient Index (GRIN) lens antenna designed with a highly efficient optimization workflow. Compound lenses offer improved scan loss ...

Practise solving trigonometric equations in degrees or radians using CAST and its period to find other solutions within the range, including multiple or compound angles and the wave function.

When we add or subtract angles, the result is called a compound angle. For example, \(30^\circ + 120^\circ\) is a compound angle. Using a calculator, we find: ...
