Microwave Kinetic Inductance Detectors (MKIDs) are photon detectors comprised of superconducting LC resonators with unique resonant frequencies corresponding to their geometrical structure. As each pixel has its own geometry, electromagnetic simulations by hand of every pixel in a kilo-pixel array are impractical. Simulating fewer pixels and interpolating in between risks reduced pixel yield in arrays due to overlapping resonant frequencies. We introduce a new software called AEM (Automated Electromagnetic MKID simulations) that automates the construction and simulation of every simulated MKID pixel in an array according to specified resonant frequencies and a range. We show automated designs to have an increased pixel yield (avoiding loses due to interpolation completely), increased accuracy in resonance frequency and values when compared to interpolated structures. We also demonstrate a simulated trial of AEM for 100 MKIDs between 4 and 8 GHz to produce MKIDs with accuracies of ± 0.2 MHz with a runtime of 10 h 45 min.
微波动态电感探测器（MKIDs）是由超导LC谐振器组成的光子探测器，其独特的谐振频率与其几何结构相对应。由于每个像素都有自己的几何形状，手动对千像素阵列中的每个像素进行电磁模拟是不切实际的。模拟较少的像素并在其间进行插值，会因谐振频率重叠而导致阵列中像素成品率降低。我们引入了一种名为AEM（自动电磁MKID模拟）的新软件，该软件可根据指定的谐振频率和范围，自动构建和模拟阵列中每个模拟的MKID像素。我们展示了自动设计的像素成品率有所提高（完全避免了因插值导致的损失），与插值结构相比，谐振频率和值的准确性也有所提高。我们还展示了对AEM在4至8 GHz之间的100个MKIDs进行的模拟试验，以生产精度为±0.2 MHz的MKIDs，运行时间为10小时45分钟。
