A 3 epochs JVLA observations of the transition disk DMTau spatially resolved the distribution of free-free emission comma which varied day-by-day and may be phased with the spinning of the host PMS star. The variation is interpreted by photon propagation comma with the disk illuminated by beamed X-ray emission from the host PMS star comma possibly due to a tilted strong stellar magnetic dipole. The JVLA Ku band A-config. and XMM-Newton monitoring for 8 consecutive days coordinated with ground based optical observations comma covering one rotational period of the host PMS star comma will resolve how the spatial distribution-flux of the radio emission correlate with the optical-UV-X-ray light curves
