Query: Radiation from Kinetic Poynting Flux Acceleration   We derive analytic formulas for the power output and critical frequency of
radiation by electrons accelerated by relativistic kinetic Poynting flux, and
validate these results with Particle-In-Cell plasma simulations. We find that
the in-situ radiation power output and critical frequency are much below those
predicted by the classical synchrotron formulae. We discuss potential
astrophysical applications of these results.
