【摘要】 本文给出存在任意两种均匀各向同性媒质分界面时,计算线天线的输入阻抗和辐射场的数学模型。针对地质工程的实际情况,计算了地下天线输入阻抗和辐射场随深度的变化。水下天线辐射场的测量结果验证了数学模型的正确性。更多还原

【Abstract】 A mathematicai model for calculating the fields of a wire antenna in the presence of an interface between two different homogreneous isotropic media is developed.The basic formulation is given.A method for improving the convergence of Sommerfeld integrals is described.The input impedance and the field distribution under the ground surface for different antenna depth are calculated.The measured result in a water tank verifies the mathematical model.更多还原
