In recent years, physical systems described by non-Hermitian Hamiltonians have been actively studied, but there are few studies on physical phenomena due to singular eigenstates at EPs. In this work, we propose the formation of a Huygens dipole due to the singular eigenstate of the EP in a coupled plasmonic resonator system. In this system, flip of the sign of coupling constant, which is generally difficult in photonic systems, is realized by using dipole-dipole interaction, and the radiation direction of the Huygens dipole can be switched.
