Since the concept of invisible cloak was proposed by Pendry and Leonhardt in 2006, many researchers have applied the theory of coordinate transformation to thermodynamics and overcome the complexity of inhomogeneous and anisotropic of material parameters. However, only two-dimensional(2 D) thermal illusion devices are researched recently. According to this situation, our study focuses on three-dimensional(3 D) thermal illusion devices including shrinker(or invisible cloak),concentrator, amplifier, reshaper, and rotator with arbitrary shape in a general way. In this paper, the corresponding material parameters of thermal illusion devices mentioned above are derived based on the theory of transformation thermodynamics and the simulated results agree well with the theoretical derivations. In addition, the conventional invisible cloak just controls the temperature gradient rather than the temperature value which is more concerned in physical applications. Here,we find that the temperature value of the cloaked object can be controlled by adjusting the location of the original point of the coordinate system.

The paper tries to analyze women characters in Tennessee Williams’ Drama The Glass Menagerie. Laura and Amanda, the daughter and the mother, represent the delicate and fragile southern female images. They both feel desperate about the reality and retreat to their own world of illusions. Laura, because of her crippled body, cannot face the ordinary problems of life and withdraws into the world of glass animals. Amanda Wingfield is unable to face the harsh struggle for survival, constantly retreats to her past memories.

Reusable reciprocal invisibility and phantom device is proposed and designed based on multi-folded transformation optics and equivalent components. In comparison with the reported reciprocal invisibility cloaks, the material parameters of the device presented here are homogeneous, and the hiding of the target object does not require any “anti-object” at all,which dramatically breaks through the limitations of the “anti-object” design in previous reciprocal cloak design. Perfectly illusion effect is also found by reasonably setting the material parameters of the restored medium of the device, which can be used to confuse detection radars while hiding target objects. Last but not least, the proposed device has an open structure,which enables the target object enclosed by the device to perform material exchange and simplex transfer of information with the outside world through open channels. In other words, the proposed device has a reusable function, enabling stealth or phantom of new target objects without changing any parameters of the device.
