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 \(\overrightarrow{\mathrm{\underline E}}\) 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 \(\overrightarrow{\mathrm{\underline E}}\) dominate all other terms for both \(\overrightarrow{\mathrm{\underline E}}\) (10.2.6) and \(\overrightarrow{\mathrm{\underline H}}\) (10.2.5), so we are left primarily with \(\overrightarrow{\mathrm{\underline E}}\) :
