Polarization controlling method in reconfigurable graphene-based patch four-leaf clover-shaped antenna
TL;DR: In this paper, a four-leaf clover-shaped reconfigurable patch antenna based on graphene is presented, which is designed in such a way that each of the different parts of the antenna structure is impacted by chemical potential variations and as a result, can create a decisive radiation performance in the far field for the designed antenna.

The rise of graphene
TL;DR: Owing to its unusual electronic spectrum, graphene has led to the emergence of a new paradigm of 'relativistic' condensed-matter physics, where quantum relativistic phenomena can now be mimicked and tested in table-top experiments.

TL;DR: It is shown that graphene grows in a self-limiting way on copper films as large-area sheets (one square centimeter) from methane through a chemical vapor deposition process, and graphene film transfer processes to arbitrary substrates showed electron mobilities as high as 4050 square centimeters per volt per second at room temperature.

TL;DR: The direct synthesis of large-scale graphene films using chemical vapour deposition on thin nickel layers is reported, and two different methods of patterning the films and transferring them to arbitrary substrates are presented, implying that the quality of graphene grown by chemical vapours is as high as mechanically cleaved graphene.
