A cylindrical wave expansion method is developed to obtain the scattering field for an ideal
two-dimensional cylindrical invisibility cloak. A near-ideal model of the invisibility cloak is set up
to solve the boundary problem at the inner boundary of the cloak shell. We confirm t ...

It was proposed that perfect invisibility cloaks can be constructed for hiding objects from electromagnetic
illumination (Pendry et al., Science 312, p. 1780). The cylindrical cloaks experimentally
demonstrated (Schurig et al., Science 314, p. 997) and theoretically proposed (Cai ...

ZEUS is a family of Eulerian (grid based) Magneto-Hydrodynamic codes
(MHD) for use in astrophysics, described in a series of papers by Stone
and Norman (1, 2, 3).
It may be used in Cartesian (XYZ),
cylindrical (ZRP), and spherical (RTP) coordinates.

In an electromagnetic cloak based on a transformation approach, reduced sets of material properties
In an electromagnetic cloak based on a transformation approach, reduced sets of
material properties are generally favored due to their easier implementation in reality,
although a seemingly inevitable drawback of undesired reflection exists in such cloaks.
Here we suggest using h ...

基于单片机的数显外锥角度游标卡尺的设计
锥形零件因其结构特点而应用广泛,但锥角测量方法要么复杂要么仅作定性测量。本文以桂林天目数显游标卡尺为基体进行扩展,把两个外测量爪改造成直径不等的两个同轴圆柱环,测量时把两个圆柱环套在被测锥体上,由卡尺输出的轴向尺寸结合两个圆柱环直径尺寸,一并输入单片机模块,由C语言程序实现锥度角度转换 ...

We analyze, both analytically and numerically, the effectiveness
of cloaking an infinite cylinder from observations by electromagnetic
waves in three dimensions. We show that, as truncated approximations
of the ideal permittivity and permeability tensors tend towards
the singular ...
