In the table shown, List I and List II, respectively, contain terms appearing on the left-hand side and the right-hand side of Maxwell’s equations (in their standard form). Match the left-hand side with the corresponding right-hand side.

If the vector function $\vec{F}=\widehat{a_x}\left(3y-k_{1}z\right)+\widehat{a_y}\left(k_{2}x-2z\right)-\widehat{a_z}\left(k_{3}y+z\right)$ is irrotational, then the values of the constants k₁, k₂ and k₃, respectively, are

The directivity of an antenna array can be increased by adding more antenna elements, as a larger number of elements:

If a right-handed circularly polarized wave is incident normally on a plane perfect conductor, then the reflected wave will be
