according to which the field of ultra short waves beyond the 

 horizon could be calculated (1935-1936). Wwedensky's publi- 

 cations on the propagation of ultra short waves are: Basis of 

 the Theory of Propagation of Radiowaves (1934); Propagation 

 of Ultra Short Waves (1934); Propagation of Ultra Short Waves 

 (1938; together with A. G. Arenberg). His investigations in 

 magnetism are presented in the monograph, Contemporary 

 Study of Magnetism (1929; together with Academician G. S. 

 Landsberg).
