  In this study, we investigate the feasibility of designing reconfigurable
transmitting metasurfaces through the use of Drude-like scatterers with purely
electric response. Theoretical and numerical analyses are provided to
demonstrate that the response of spherical Drude-like scatterers can be
tailored to achieve complete transmission, satisfying a generalized Kerker's
condition at half of their plasma frequency. This phenomenon, which arises from
the co-excitation of the electric dipole and the electric quadrupole within the
scatterer, also exhibits moderate broadband performance. Subsequently, we
present the application of these particles as meta-atoms in the design of
reconfigurable multipolar Huygens metasurfaces, outlining the technical
prerequisites for achieving effective beam-steering capabilities. Finally, we
explore a plausible implementation of these low-loss Drude-like scatterers at
microwave frequencies using plasma discharges. Our findings propose an
alternative avenue for Huygens metasurface designs, distinct from established
approaches relying on dipolar meta-atoms or on core-shell geometries. Unlike
these conventional methods, our approach fosters seamless integration of
reconfigurability strategies in beam-steering devices.
