An intelligent reflecting surface (IRS) can adaptively adjust the phase shifts of its reflecting
units to strengthen the desired signal and/or suppress the undesired signal. In this letter, we …

In this paper, we propose to utilize intelligent reflecting surfaces (IRSs) for enhancing the
physical layer security of wireless communications systems. In particular, an IRS-assisted …

In this letter, we investigate whether the use of artificial noise (AN) is helpful to enhance the
secrecy rate of an intelligent reflecting surface (IRS) assisted wireless communication …

In this paper, intelligent reflecting surfaces (IRSs) are employed to enhance the physical
layer security in a challenging radio environment. In particular, a multi-antenna access point …
