This paper addresses the problem of determining the optimal robot trajectory for localizing a robot follower in a leader-follower formation using robot-to-robot distance or bearing measurements. In particular, maintaining a perfect formation has been shown to reduce the localization accuracy (as compared to moving randomly), or even leads to loss of observability when only distance or bearing measurements...
With the deformation theory of continuum mechanics, we extend the coordinate transformation method to design arbitrary transformation metamaterials, which are inherently transparent for electromagnetic waves. In the experiment, the metamaterial capable of bending waves is verified. The transparency phenomenon based on the field cancellation effect is also discussed. The composites fabricated with...
A non-charge-sheet surface-potential-based compact drain-current model for long-channel undoped gate-all-around (GAA) silicon-nanowire (SiNW) MOSFETs is developed. The surface-potential equation is derived from cylindrical Poisson equation for undoped silicon and solved iteratively with a very good initial guess to reach equation residue below 10-16 V within a few iterations. The single-piece current...
