We explore the field enhancement and temporal response of coupled bi-metal Ag/Au core-shell nanoparticle antennas. The bimetal antennas exhibit ultra-broadband resonances and allow exploiting the local field enhancement for few-cycle laser applications such as elements with an ultrafast response in nanoplasmonic device. We study dimer, trimer and heptamer arrangements and find that the Ag/Au core-shell trimer shows that a very high enhancement factor with an amplitude exceeds 120, but still facilitates an ultrafast response. Such systems may be ideal for the generation of attosecond light pulses based on high harmonic generation by employing nanoplasmonic field enhancement.
