The Electron-Ion Collider (EIC) to be built at Brookhaven National Laboratory is a high luminosity accelerator facility colliding polarized electron beam with different ion species ranging from lighter nuclei (proton, deuterium) to heavier nuclei (gold, uranium). Design of a stripline injection kicker for the Hadron Storage Ring (HSR) of EIC for beams with beam rigidity of 81 T-m poses some technical challenges due to expected high feedthrough voltages, short bunch spacing, and high peak current of EIC. This talk will focus on the optimization of the stripline injection kicker. Starting from the 2D cross-section design which includes the selection of electrodes shape, we describe the optimization of the kicker's cross-section and the techniques that we employed to optimize its 3D geometry. In addition, we present the simulation results for the beam coupling impedance and Time Domain Reflection (TDR). Finally, we will show the maximum surface electric field corresponds to the feedthrough voltage we require and the surface heating due to the circulating beam.
