In this Letter, we propose a class of plasmon that exhibits properties such as autofocusing and self-bending. In a butterfly plasmon, several new dimensions of focus modulation are introduced. By adjusting its initial phase, the position, the length, the intensity, and the bending direction of the plasmonic focus can be precisely controlled, demonstrating a high degree of tunability.

A type of circular Airyprime function of complex-variable Gaussian vortex (AFCGV) wave packets in a strongly nonlocal nonlinear medium is introduced numerically, combining the properties of helicity states and abrupt autofocusing. We investigate the effects of the chirp factor, distribution parameter, and decay factor on the AFCGV wave packets in the strongly nonlocal nonlinear medium.
