Constructions of strongly regular Cayley graphs using index four Gauss sums

We give a construction of strongly regular Cayley graphs on finite fields $\mathbb{F}_{q}$ by using union of cyclotomic classes and index 4 Gauss sums. In particular, we obtain two infinite families of strongly regular graphs with new parameters.
