This thesis has its focus on the local manipulation and control of dipolar dominated spin waves (SW) by means of changing the magnetic landscape, experimentally observed by Time Resolved Magneto Optical Kerr Microscopy. We present a SW propagation through a diffraction grating and observe not only a caustic like SW emission, but also a transmission stop band for SWs. Furthermore, we demonstrate the effect of normal metals in proximity to a magnetic insulator on the SW propagation, as well as the characteristic of magnetization dynamics excited by a variety of ultrashort rf-pulses.
