If we examine the near fields radiated by a Hertzian dipole close to the origin where kr << 1, then the (kr) −2 terms in the expression (10.2.7) for →E_ dominate...If we examine the near fields radiated by a Hertzian dipole close to the origin where kr << 1, then the (kr) −2 terms in the expression (10.2.7) for →E_ dominate all other terms for both →E_ (10.2.6) and →H_ (10.2.5), so we are left primarily with →E_ :
