Near-fields of Butterfly Nanoantenna Arrays: A Simulation Study

Journal of Applied Computational Electromagnetics Society (ACES)


Optical nanoantennas demonstrate the ability to confine and enhance electromagnetic fields. This ability makes the nanoantennas essential tools for nano-optical devices and high-resolution microscopy. The response and resonances of the antennas are determined by the shape, size, material and the wavelength of light. In this paper we simulated the propagation and interaction of visible light with butterfly nanoantenna arrays using the finite-difference time-domain (FDTD) method. Experimental results measured on the same nanoantenna arrays by scanning near-field microscopy (SNOM) are reported in a separate paper.
