Above-Threshold Photoemission of Compound Nanoantennas Irradiated by Femtosecond Laser Pulses

详细

A theoretical study of electron emission processes that occur at interaction of femtosecond laser pulses with bowtie compound nanoantennas is performed. A numerical analysis is conducted of the dependences of the spectra of ejected electrons on the features of the light pulses for different geometric parameters of the antennas. The calculation results show that asymmetric nanoantennas have distinct advantages over symmetric configurations of the elements of compound antennas.
