| Abstract: | We investigate a possibility that non-thermal X-ray emission in a supernova remnant(SNR) is produced by jitter radiation,
which is the analogue of synchrotron radiation in small-scale random magnetic fields. We can fit the multi-wavelength data
of SNRs RX J1713.7-3946 (G347.3-0.5) and RX J0852.0-4622 (G266.6-1.2) by constructing pure jitter and inverse Compton (IC)
emission models. We find that the physical fit parameters of random magnetic fields take values of several tens of μG strength
and of the order of ∼107 cm correlation length. These properties of random magnetic fields in collisionless shock of SNRs are discussed.
