Query: Nonreciprocal and non-Hermitian material response inspired by
  semiconductor transistors   Here, inspired by the operation of conventional semiconductor transistors, we
introduce a novel class of bulk materials with nonreciprocal and non-Hermitian
electromagnetic response. Our analysis shows that material nonlinearities
combined with a static electric bias may lead to a linearized permittivity
tensor that lacks the Hermitian and transpose symmetries. Remarkably, the
material can either dissipate or generate energy, depending on the relative
phase of the electric field components. We introduce a simple design for an
electromagnetic isolator based on an idealized "MOSFET-metamaterial" and show
that its performance can in principle surpass conventional Faraday isolators
due to the material gain. Furthermore, it is suggested that analogous material
responses may be engineered in natural media in nonequilibrium situations. Our
solution determines an entirely novel paradigm to break the electromagnetic
reciprocity in a bulk nonlinear material using a static electric bias.
