Magnetic skyrmions, particle-like magnetic textures characterized by a quantized topological invariant in magnets with broken spatial inversion symmetry, are currently attracting enormous research interest in the field of spintronics. Recent intensive studies have uncovered that magnetic skyrmions exhibit rich physical phenomena and device functions originating from their topological nature. In this chapter, we discuss microwave-induced dynamical phenomena of magnetic skyrmions associated with their peculiar spin-wave modes. In particular, we focus on a situation that the magnetic skyrmions are confined in a quasi-two-dimensional thin-plate magnet under application of a static magnetic field tilted from the perpendicular direction. It is theoretically demonstrated that the spin-wave excitations of these magnetic skyrmions by microwave irradiation give rise to translational motion of the skyrmions and generation of the DC electric voltages. These phenomena indicate that rich physics and functionalities are hidden in the microwave-driven skyrmion dynamics under a tilted magnetic field.
