Question

A certain guided wave travels through air with the following magnetic field
H=10+ y cos(157x) sin[(67×10° rad/s)t - Bz] [A/m]
(0.3)
Find the associated and B. There are a couple ways to solve this problem. Note:
this is NOT a plane wave, and be sure to understand why. Nevertheless it IS a valid
solution of Maxwell's equations. You will see how guided waves like this come about

a) The second of Maxwell's equations states that the divergence of the magnetic flux density is always zero, i.e. V B 0. What does this tell you generally about the distribution of magnetic flux? Describe the impact of a non-zero value on the right-hand-side of Maxwell's second equation. b) With reference to Figure 2, the Biot-Savart law can be used to show that the magnetic flux density due to a straight current-carrying wire of finite length is given by Hol %3D (cos a2 - cos a,) âg 477 Figure 2 Show that this expression is consistent with Ampère's law when applied to a long straight current carrying conductor. c) Figure 3 depicts a section of printed circuit carrying a current / of (100 + 10X) mA.

A number N of plane waves are travelling parallel; the waves share a common wavevector k and common direction of electric field vector along unit vector û, but each wave has its own distinct amplitude Eo and phase difference &;.
