Fourier transform of $\frac{t}{(a^2+t^2)^{3/2}}$.

72 Views Asked by At

Im trying to find the Fourier transform of the function: $$\frac{t}{\left(t^2+a^2\right)^{\frac{3}{2}}};$$ As well the Fourier transform of the function: $$\frac{1}{\left(t^2+a^2\right)^{\frac{3}{2}}}.$$ It looks very similar to the first modified Bessel function but not quite, I wondered if there is an analytic expression for that transformation.
