| Abstract |
| The control of propagation of electromagnetic waves is an important issue in 6G communications. Metasurfaces are used efficiently in controlling propagation of electromagnetic waves. The metasurface is an array of unit cells. When a plane wave is incident on the unit cell, it will be reflected with a change of phase. The amount of phase change depends upon cell geometry and dimensions. Cells can be designed to give phase change of values ranging from 0 to 360o. Unit cells are arranged in the form of columns. The unit cells of one column are similar. There is a phase difference Φ between unit cells of one column and unit cells of the neighbouring column. In this paper six values of the phase difference Φ are considered. A normally incident plane wave is reflected from the metasurface. The angles of reflection were found using generalized Snell’s law. The results are validated using antenna array theory. Excellent agreement between the two results is obtained. |
