Accurate Characterization of Radiation from Interconnects on Interposer at mmWave Frequencies

An electromagnetic interference (EMI) assessment of mmWave interposers becomes increasingly important as the need for heterogeneous systems increases. However, the small size and complexity of these platforms make it more difficult to accurately measure them and, thus, a dedicated set-up to isolate the interposer’s emission is required. In this contribution, we first show experimentally that […]

Comparison of two novel integral equation approaches for lossy conductor modeling

In this paper, we take a closer look at two novel boundary integral equation methods that are ideally suitable for modeling good but lossy conductors. The first method leverages the Calderón identities to precondition the homogeneous Poincaré-Steklov operator for high dielectric contrast materials. The second technique constructs an alternative formulation of the Poincaré-Steklov operator based […]
