    • The process of modeling a complex two-dimensional periodic structure is improved by selectively truncating the Fourier expansion used in the calculation of resulting scatter signature from the model. The Fourier expansion is selectively truncated by determining the contribution for each harmonic order in the Fourier transform of the permittivity function and retaining the harmonic orders with a contribution that is above a threshold. The Fourier space may be compressed so that only the selected harmonic orders are used, thereby reducing the required memory and calculation times. The compressed Fourier space may be used in a real-time analysis of a sample or to generate a library that is used in the analysis of a sample.

    • Embodiments of the present invention provide a method and device for traffic forwarding in a stacking apparatus which includes multiple member devices. The method includes: obtaining, by a member device, a forwarding table size of each member device in the stacking apparatus; choosing a member device having the largest forwarding table as a proxy device when a forwarding table of another member device in the stacking apparatus is larger than that of the member device; transmitting all or part of to-be-forwarded traffic to the proxy device which performs traffic forwarding. According to the present invention, forwarding capability of member devices having larger forwarding tables is utilized for providing proxy forwarding for member device having smaller forwarding tables, so that forwarding sizes of the member devices having different forwarding table sizes in the stacking apparatus are unified and forwarding capabilities of the member devices in the stacking apparatus are fully used.
