We provide an investigation on the analogy of plasmon induced transparency (PIT) in plasmonic waveguide numerically and theoretically. A simplified Coupled-Mode theory model is used to demonstrate the PIT-like effect in a system consisting of two detuned U-resonators (DURs) back coupled to a metal-dielectric-metal (MOM) waveguide. The detuned wavelength 5 is introduced by the simplified model qualitatively due to the structural design. The sensitivity of wavelength and the trade-off between Q-factor and transmission maxima are considered. Finally, the observed slow light effect in our system guarantees a low group velocity which has potential application in nano-filter and optical buffer.
