摘要

─在混响室中，边界场分布的解析解存在于非常有限的情况下。对于任意形状的物体，可能不存在解析解。为了解决这一问题，提出了一种求得随机漫射波环境中任意形状物体附近平均场分布的通用数值方法。该方法结合了全波法和蒙特卡罗法;对数值计算结果进行了验证，并与解析方程结果进行了比较。该方法可应用于具有一般材料特性的任意形状物体。索引项─边界场、蒙特卡罗模拟、平面波模型、混响室。

Simulating Boundary Fields of Arbitrary-shaped Objects in a Reverberation Chamber

─ In a reverberation chamber, analytical solutions exist in very limited scenarios for the distribution of the boundary fields. For arbitrary-shaped objects, analytical solutions may not exist. To solve this problem, a general numerical method is proposed to obtain the mean field distribution near arbitrary-shaped objects in a random diffused-wave environment. The proposed method combines the full-wave method and the Monte-Carlo method; the numerical results are validated and compared with that from analytical equations. The proposed method can be applied to arbitrary-shaped objects with general material properties. Index Terms ─ Boundary fields, Monte-Carlo simulation, plane wave model, reverberation chamber.

期刊介绍： The ACES Journal is devoted to the exchange of information in computational electromagnetics, to the advancement of the state of the art, and to the promotion of related technical activities. A primary objective of the information exchange is the elimination of the need to "re-invent the wheel" to solve a previously solved computational problem in electrical engineering, physics, or related fields of study. The ACES Journal welcomes original, previously unpublished papers, relating to applied computational electromagnetics. All papers are refereed. A unique feature of ACES Journal is the publication of unsuccessful efforts in applied computational electromagnetics. Publication of such material provides a means to discuss problem areas in electromagnetic modeling. Manuscripts representing an unsuccessful application or negative result in computational electromagnetics is considered for publication only if a reasonable expectation of success (and a reasonable effort) are reflected. The technical activities promoted by this publication include code validation, performance analysis, and input/output standardization; code or technique optimization and error minimization; innovations in solution technique or in data input/output; identification of new applications for electromagnetics modeling codes and techniques; integration of computational electromagnetics techniques with new computer architectures; and correlation of computational parameters with physical mechanisms.
