Title: Transverse plasmon mode in a screened two-dimensional electron system

The dispersion and damping of the transverse plasmon mode in a screened two-dimensional (2D) electron system are theoretically studied. It is shown that the transverse plasmon mode has a much larger quality factor and a smaller retardation factor at terahertz (THz) frequencies in comparison with those known for the longitudinal plasmon mode. In addition, the electric dipole moment of the transverse plasmon mode in the screened 2D electron system can be comparable with the dipole moment of the longitudinal plasmon mode. These properties of the transverse plasmon mode make it attractive for use in plasmon devices of the THz frequency range.
