Abstract

The paper describes a multi-domain CAD platform, exploiting nonlinear and electromagnetic software tools, for the rigorous analysis of time-modulated linear arrays. A circuit-level analysis of the non-radiating network including the time-modulated nonlinear switches is carried out by means of the Harmonic-Balance (HB) method. The corresponding nonlinear regime is then used to evaluate the actual far-field radiated by the array in the real operating conditions. Examples with different switch modulation patterns are presented in order to demonstrate the effectiveness of the tool and also the impact of simplifying assumptions typical of previous approaches.
时间调制阵列仿真的非线性/电磁方法
本文描述了一个多域CAD平台,利用非线性和电磁软件工具,对时调制线性阵列进行严格分析。采用谐波平衡法对含时调制非线性开关的非辐射网络进行了电路级分析。然后用相应的非线性区来计算阵列在实际工作条件下的实际远场辐射。给出了具有不同开关调制模式的示例,以证明该工具的有效性以及简化假设的影响。
