Ultra-Sensitive Radio Frequency Biosensor at an Exceptional Point of Degeneracy induced by Time Modulation
Hamidreza Kazemi, Amirhossein Hajiaghajani, Mohamed Y. Nada +4
We exploit the premises of exceptional points of degeneracy (EPDs) induced in linear time-periodic (LTP) systems to achieve extremely sensitive biosensors. The EPD is formed in a s…
Experimental Demonstration of Exceptional Points of Degeneracy in Linear Time Periodic Systems and Exceptional Sensitivity
Hamidreza Kazemi, Mohamed Y. Nada, Alireza Nikzamir +2
We present the experimental demonstration of the occurrence of exceptional points of degeneracy (EPDs) in a single resonator by introducing a linear time-periodic variation of one…
Illusion Mechanisms with Cylindrical Metasurfaces: A General Synthesis Approach
Mahdi Safari, Hamidreza Kazemi, Ali Abdolali +2
We explore the use of cylindrical metasurfaces in providing several illusion mechanisms including scattering cancellation and creating fictitious line sources. We present the gener…
Simultaneous Perfect Bending and Polarization Rotation of Electromagnetic Wavefront using Chiral Gradient Metasurfaces
Hamidreza Kazemi, Mohammad Albooyeh, Filippo Capolino
We introduce chiral gradient metasurfaces that allow perfect transmission of all the incident wave into a desired direction and simultaneous perfect rotation of the polarization of…
