N2 - In this paper, we propose a surrogate model for both forward and inverse modeling with complex-valued neural networks. The complex domain offers the benefits of higher functionality and better representation. To that end, we propose a deep complex dense network (DNet) by introducing complex dense blocks built with fully-connected layers that support complex operations. We further propose an inverse optimization objective that minimizes the modeling error while optimizing the design space parameters that achieve the target specifications. We apply our proposed approach for the design of a sub-THz patch antenna-in-package operating at 140 GHz frequency band.
