The previous theoretical analysis by the present author on the propagation of whistler radio waves along an enhanced or depressed magnetoplasma slab imbedded in an infinite magnetoplasma is extended to include the general case of an arbitrary thickness of the slab. As a result, two different types of completely guided waves are found to exist in general. The one guided wave is essentially a surface wave trapped along an interface between two semi‐infinite plasmas of different plasma densities, while the other guided wave is a duct type of surface wave in which the whistler plane wave is predominantly propagated inside the slab by the successive total reflections at the walls of the slab and is propagated along the depressed plasma slab only. Dispersion properties of these completely guided waves are studied in detail.
