dc.description.abstract	We recently presented evidence (Rajaguru et al. 2013) that seismic halos around expanding magnetic structures in the lower solar atmosphere are related to the acoustic to magnetoacoustic wave conversions, using multi-height data from Helioseismic and Magnetic Imager (HMI) and Atmospheric Imaging Assembly (AIA: 1700 and 1600 Å channels) onboard Solar Dynamics Observatory (SDO). Using the same data, we present and discuss here further evidence through analyses of maps of phase-shifts between observables from different heights and their correspondence with oscillation power. The phase shift maps provide more direct signatures of reflection and refraction of (magneto-)acoustic wave modes.	en_US
