  We find new 1/8-BPS giant graviton solutions in $AdS_5 \times S^5$, carrying
three angular momenta along $S^5$, and investigate their properties.
Especially, we show that nonzero worldvolume gauge fields are admitted
preserving supersymmetry. These gauge field modes can be viewed as
electromagnetic waves along the compact D3 brane, whose Poynting vector
contributes to the BPS angular momenta. We also analyze the (nearly-)spherical
giant gravitons with worldvolume gauge fields in detail. Expressing the $S^3$
in Hopf fibration ($S^1$ fibred over $S^2$), the wave propagates along the
$S^1$ fiber.
