This paper reports that a general method of designing invisible cloaks is using variant constitutive material parameters to realize the space transformation. A hollow region can be hidden after this transformation. It...

The method of designing electromagnetic invisible cloaks is usually based on the form-invariance of Maxwell's equations in coordinate transformation. The exterior boundary of a cylindrical invisible cloak is unchange...

A new metal-organic framework, {Zn[Zn3(BTA)3(μ3-OH)(H2O)3]2}n 1, has been synthesized under hydrothermal reaction of ZnCl2 and bis(5-tetrazolyl)amine (H2BTA), and characterized by elemental analysis, FT-IR,...

We simplify the material parameter equation for elliptical cylinder cloaks under transverse-electric and transverse- magnetic models, respectively, and confirm these simplified equations by numerical simulations. As a...

By making a comparison between the acoustic equations and the 2-dimensional (2D) Maxwell equations, we obtain the material parameter equations (MPE) for acoustic elliptical cylindrical cloaks. Both the theoretical...
