3.14| A certain light-emitting diode (LED) is centered at the origin with its surface in the xy plane. At far distances, the LED appears as a point, but the glowing surface geometry produces a far-field radiation pattern that follows a raised cosine law: that is, the optical power (flux) density in watts/m² is given in spherical coordinates by Pa = Po cos² 0 a, watts/m? 2nr2 where 0 is the ...
