abstract = {We have developed an interdigited electrode structure for
applying a static electric field to a ferroelectric thin
film, which enables nearly full transmission of a
perpendicularly polarized terahertz wave. This approach has
been used to determine the electric field dependence of the
complex permittivity of a SrTiO3 thin film on a sapphire
substrate up to about 2 THz employing time-domain terahertz
spectroscopy. We have demonstrated up to $10\%$ variation of
the film permittivity at 300 GHz at room temperature induced
by an applied electric field of 100 kV/cm. No dielectric
dispersion is observed between 1 MHz and about 500 GHz. The
field-induced changes are attributed to soft mode hardening.
