Abstract :
Spatiotemporal collapse of spin-dipole wave (SDW) pulses of millimeter wave range is investigated theoretically. The dispersion and diffraction coefficients of SDW have been calculated, when the retardation has been taken into account. It is demonstrated that YIG films are suitable for observing the collapse in millimeter wave range, due to low dissipation and quite high values of dispersion and diffraction coefficients. Numerical simulations have been confirmed this result.
