A Novel Parameterized Scattering Center Model for Complex Honeycomb Absorbers

To address the modeling challenges and high computational complexity associated with full-wave algorithms for honeycomb absorbing materials, this paper proposes a parametric scattering center model for complex honeycomb absorbing structures. The model derives the generalized reflection coefficient of the homogenized honeycomb structure using the geometrical optics (GO) method to characterize the amplitude factor of the scattering center model. Subsequently, full-wave method data is used to optimize the parameters of the scattering center model. Validation results indicate that the scattering characteristics computed with the proposed model are highly consistent with those obtained using multilevel fast multipole algorithm (MLFMA). However, our parametric model significantly improves computational efficiency and reduces memory consumption. Therefore, this method provides an innovative approach for simulating the scattering characteristics of complex honeycomb materials.
