Question

1. Show that the directivity for a source with a unidirectional power pattern given by $U = U_m \cos^n \theta$ can be expressed as $D = 2(n+1)$. U has a value only for $0 \le \theta \le \frac{\pi}{2}$ and $0 \le \phi \le 2\pi$ and is zero elsewhere.

Name: 1. Show that the directivity for a source with a unidirectional power pattern given by U = Um cos^n θ can be expressed as D = 2(n+1). U has a value only for 0 ≤θ≤(π)/(2) and 0 ≤ϕ≤ 2π and is zero elsewhere.
