avenue to improve absorption capacity [14]. Similarly, metal sulfides (metal = Sn, Fe, Mn, Co, Ni, Zn, and Cu) have received great attention as a class of semiconductor that can be used to construct heterojunctions. This is mainly because metal sulfides typically have narrow band gaps...

Visible light waves are a form of electromagnetic radio waves such as the infrared radiation, X-rays, microwaves and ultraviolet radiation. It makes us to see the different objects or substances, For example, fireflies use light to locate mates.
A compelling extension of this concept is in a class of dynamic 3D display system that coordinates morphing of the geometry of the screen with moving images projected onto it. Figure 6a and b presents a schematic illustration (Fig. 6a) and an optical image (Fig. 6b) of a setup where such...
The layered polymer matrix EMI shielding composites are a class of materials with a layered structure. The electromagnetic waves can be reflected for multiple times inside the composites due to the layered structure, thereby improving their EMI shielding performance greatly. The lightweight and flexible...
Metasurfaces are engineered surfaces that consist of subwavelength periodic elements and can be used to manipulate electromagnetic waves. Multifunctional or reconfigurable electromagnetic meta-devices based on a direct-current biasing system can be built using lumped electronic components. However, such meta...
Cell phone signals are carried through the air as microwaves. The caller’s sound is encoded in microwaves by changing the frequency of the waves. This is called frequency modulation. The encoded microwaves are sent to the cell tower through the air. From the cell tower, the waves travel to...
