Second Order Surface Analysis

Results from analyzing the curvature of a surface can be used to improve the implementation, e ciency, and e ectiveness of manufacturing and visualization of sculptured surfaces. In this paper, we develop a robust method using hybrid symbolic and numeric operators to create trimmed surfaces each of which is solely convex, concave, or saddle and partitions the original surface. The same method i...

Time-Frequency Analysis for Second-Order Attacks

Second-order side-channel attacks are used to break firstorder masking protections. A practical reason which often limits the efficiency of second-order attacks is the temporal localisation of the leaking samples. Several leakage samples must be combined which means high computational power. For second-order attacks, the computational complexity is quadratic. At CHES ’04, Waddle and Wagner intr...

Fractal FSS: a novel dual-band frequency selective surface - Antennas and Propagation, IEEE Transactions on

The multiband properties of self-similar fractals can be advantageously exploited to design multiband frequency selective surfaces (FSS). A Sierpinski dipole FSS has been analyzed and measured and the results show an interesting dual-band behavior. Furthermore a near-field measurement technique is applied to characterize the FSS response to different angles of incidence. Finally, it will be sho...

Spatial frequency selective masking of first-order and second-order motion in the absence of off-frequency `looking'

Converging evidence suggests that, at least initially, first-order (luminance defined) and second-order (e.g. contrast defined) motion are processed independently in human vision. However, adaptation studies suggest that second-order motion, like first-order motion, may be encoded by spatial frequency selective mechanisms each operating over a limited range of scales. Nonetheless, the precise p...

Equivalent Circuit Model for Square Ring Slot Frequency Selective Surface

An equivalent circuit model for predicting the frequency response of a square ring slot frequency selective surface (SRS-FSS) for normal incidence is described. The proposed FSS consists of an array of square patches centered within a wire grid. The presented circuit model is formed by the impedance of the wire grid that is parallel with the impedance of the patch array, also the mutual couplin...
