ELECTROMAGNETIC-FIELDS OF DIPOLES EFFECTED BY A SEMIINFINITE MEDIA

Expressions for electromagnetic fields generated by vertical and horizontal electric dipoles located in the air or in a lossy half-space near its boundary with air are obtained from Hertz vectors by the method of operators under the condition \n\3 much less than where 1/n is the refractive constant of the lossy space. These can be applied up to the near fields under the additional conditions, \n\2 much less than 1, and cos2 theta much less than 1, where theta is the zenith angle of the point of observation. As for recent works inclusive of expressions of lateral waves their weak points are pointed out.
