We consider impulsive excitation of slow magnetosonic standing waves in a two-dimensional hot solar coronal slab. Results of numerical simulations have revealed that initially launched pulses trigger mainly fundamental slow mode and its first harmonic, depending on the pulses' spatial location. Our parametric study has shown these slow standing waves to exhibit wave periods of about 13min. The slow standing waves are accompanied by fast modes simultaneously present in the system.
