Frequency-selective surface acoustic invisibility for three-dimensional immersed objects

This paper is focused on the study of acoustic metasurface cloaking, based on the use of appropriate ultrathin pseudo-surfaces that may act as cloaking devices for a finite range of frequencies. The technique consists in tailoring the appropriate acoustic surface impedance which cancels the scattered field of a diffracting spherical obstacle placed in the trajectory of an impinging acoustical w...

Surface wave holography on designing subwavelength metallic structures.

We report a method in the framework of surface wave holography to manipulate the electromagnetic wave on the metallic surface for realizing complicated electromagnetic wave transport functionalities in three-dimensional (3D) space. The method allows for direct determination of the metallic surface structure morphology for a given transport functionality, by means of writing desirable object inf...

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...

Three-Dimensional Surface Recognition Based on Genetic Algorithms

A robust method for 3-D surface recognition based on genetic algorithms is proposed in this paper. With the help of a specilic least square fitting algorithm, the model-based 3-1) st,rfacc recognition problem is first converted into an optimization problem. Then. a genetic algorithm is used to solve the optimal problem in order to extract general quadric surfaces. Finally. all the extracted .~u...

Three dimensional knot models based on surface laser scanning

Most machine strength grading methods of today result in limited grading accuracy and poor yield in higher strength classes. A new and more accurate grading method utilizing laser scanning technique to determine the in-plane fibre directions on board surfaces was recently approved for the European market. In this, however, no consideration is taken to the out-of-plane direction of the fibres. A...
