  In this paper, we investigate the detectability of radio emission from
exoplanets, especially hot Jupiters, which are magnified by gravitational
microlensing. Because hot Jupiters have orbital periods much shorter than the
characteristic timescale of microlensing, the magnification curve has a unique
wavy feature depending on the orbital parameters. This feature is useful to
identify radio emission from exoplanets and, in addition to magnification,
makes it easier to detect exoplanets directly. We also estimate the expected
event rate red of the detectable level of microlensed planetary radio
emissions, assuming the LOFAR and the first phase of the Square Kilometre
Array.
