商品描述

The book is devoted to the solution of one general problem of the theory of a three-dimensional quasi-stationary sinusoidal and pulse electromagnetic field. These studies, unlike many well-known works, are based on obtained exact analytical solution of the problem for the field, generated by external current sources near the conducting body with plane surface. The solution for the vector and scalar potentials, electric and magnetic intensities in the dielectric and conducting media is found without restrictions on the configuration of current sources,

properties of the media and field frequency. Some general properties of field formation for arbitrary field in the considered system are obtained (in particular, full compensation by the field of the electric charge distributed on the interface between the media, the normal component of the induced external electric field and, accordingly, the equality to zero the components both of the current density and the electric field intensity perpendicular to the interface; the non-uniform electromagnetic field decreases in depth of conducting medium faster than uniform field). It is shown that the exact analytical solution depends on the values of the parameter proportional to the ratio of the field penetration depth to the distance between the external field sources and the body. The concept of strong skin effect is extended to the case of small value of the introduced parameter. A significant simplification of the

expressions was obtained as an asymptotic expansion on this small parameter. In the case of pulsed fields approximate method gives the highest accuracy during important initial period of pulse time. For asymptotic expansion the approximate impedance boundary condition is generalized to the diffusion of non-uniform field into conducting medium. The book is intended for the researchers, postgraduate students and students specialized in theory and calculations of electromagnetic fields.

本書專注於解決三維準靜態正弦和脈衝電磁場理論中的一個一般性問題。這些研究與許多知名作品不同，基於對由外部電流源在平面表面附近產生的場的精確解析解。對於介電和導電媒介中的向量和標量勢、電場和磁場強度的解決方案，無需對電流源的配置、媒介的性質和場的頻率施加限制。獲得了一些在所考慮系統中任意場的場形成的一般性質（特別是，場對於分佈在媒介界面上的電荷的完全補償、誘導的外部電場的法向分量，以及相應地，電流密度和垂直於界面的電場強度分量均為零；不均勻電磁場在導電媒介的深度衰減速度快於均勻場）。顯示出精確的解析解依賴於與外部場源和物體之間距離的場穿透深度比值成比例的參數值。強皮膚效應的概念擴展到引入參數值較小的情況。通過對這個小參數的漸近展開，獲得了表達式的顯著簡化。在脈衝場的情況下，近似方法在脈衝時間的重要初始期間提供了最高的準確性。對於漸近展開，近似阻抗邊界條件被推廣到不均勻場在導電媒介中的擴散。本書旨在為專注於電磁場理論和計算的研究人員、研究生和學生提供參考。
