how one can deduce from maxwell equations that an accelerating charged particle radiates electromagnetic waves? from which equations it is derived?

Any static charge will have a static field.
Now, if charge starts moving it will generate a time varying field given by maxwell's time harmonic equations

Code:

curl[B]E[/B] = -j\[\omega\]\[\mu\][B]H[/B]
curl[B]H[/B] = (\[\sigma\] + j\[\omega\]\[\mu\]\[\varepsilon\])[B]E[/B]

Now taking curl (roughly you can think of it as diffrentiating wrt time) & doing some math, & assuming the conditions for free space we get the wave equations.

Code:

\[\nabla\][SUP]2[/SUP] \[\vec{ E}\] = \[\mu\]\[\varepsilon\]\[ \frac{\partial^2 E}{\partial (t^2)}\] 

\[\nabla\][SUP]2[/SUP]\[\vec{ H}\] = \[\mu\]\[\varepsilon\]\[ \frac{\partial^2 H }{\partial (t^2) }\]
