We propose a new solution for high hot–spot density creation by coupling a particle and a cavity in a structure dubbed a plasmonic enhanced particle–cavity (PEP–C) antenna. In comparison to analogous particle–based dimer antenna structures, the PEP–C allows both a higher maximum field and an order–of–magnitude higher hot–spot density. In addition, the hot–spots of the PEP–C antenna can be precisely controlled, resulting in increased reliability. We elucidate the photonic characteristics of the PEP–C antenna and show tuning and optimization through choice of geometric parameters. These properties make the PEP–C antenna an excellent candidate for plasmonic–based biomolecular sensors.
