  This work utilizes established models of synchrotron-powered light curves for
core-collapse supernovae in dense circumstellar environments, namely type IIn
and Ibn, to demonstrate the potential for detecting millimeter emission from
these events. The progenitor types of these supernovae are still an open
question, but using the synchrotron light curves as probes for the
circumstellar environments could shed light on the mass-loss histories of the
progenitors and discern between different theories. Observations in millimeter
bands are particularly fruitful, as they probe regions at smaller radii and
higher ambient densities, where centimeter emission tends to be self-absorbed.
In our application of these light curves, we explore a diversity of progenitor
types and mass-loss profiles to understand their effects on the light curve
shapes. Additionally, we fit model parameters to the 8\,GHz light curve of type
IIn supernova 2006jd and then create millimeter light curves using these
parameters to show the possibility of detecting an early millimeter peak from
such an event. We predict that next generation millimeter surveys will possess
the capability to detect nearby and extreme events. However, there is a
pressing need for millimeter follow-up of optically discovered interacting
supernovae to more completely sample the true population.
