  We report the polarization-dependent electromagnetic response from a series
of novel terahertz (THz) metasurfaces where asymmetry is introduced through the
displacement of two adjacent metallic arms separated by a distance $\delta$.
For all polarization states, the symmetric metasurface exhibits a low quality
(Q) factor fundamental dipole mode. By breaking the symmetry, we experimentally
observe a secondary dipole-like mode with a Q factor nearly $9\times$ higher
than the fundamental resonance. As $\delta$ increases, the fundamental dipole
mode $f_{1}$ redshifts and the secondary mode $f_{2}$ blueshifts creating a
highly transmissive spectral window. Polarization-dependent measurements reveal
a full suppression of $f_{2}$ for all asymmetries at $\theta \geq 60^\circ$.
Furthermore, at $\delta \geq 60 \text{ }\mu\text{m}$, we observe a polarization
selective electromagnetic induced transparency (EIT) for the fundamental mode.
This work paves the way for applications in filtering, sensing and slow-light
devices common to other high Q factor THz metasurfaces with EIT-like response.
