Full-Wave Harmonic Balance Framework for Dispersive Time-Varying Photonic Structures
Mohammad R. Tavakol, Wenshan Cai
Time-varying photonic structures redistribute electromagnetic energy among Floquet harmonics, enabling frequency conversion, nonreciprocity, parametric gain, and dynamic wavefront…
Nonreciprocal Negative Refraction Enabled by Photonic Time Crystals
Mohammad R. Tavakol, Wenshan Cai
We propose and theoretically demonstrate nonreciprocal negative refraction enabled by time-varying photonic structures. By engineering temporal modulations at the interfaces of hyp…
Electromagnetic Field Tapering in the High-Roughness Substrates Coated by a Thin Film of Manganese: A Lithography-Free Approach to Ultra-Broadband, Wide-Angle, UV to FIR Perfect Absorption
Majid Aalizadeh, Mohammad Reza Tavakol, Amin Khavasi +2
Metallic layers are known to be used for the suppression of wave transmission when their thickness is sufficiently higher than the skin depth of metal. If in addition to blocking t…
Two Dimensional Edge Detection by Guided Mode Resonant Metasurface
Amirhossein Saba, Mohammad Reza Tavakol, Parisa Karimi-Khoozani +1
In this letter, a new approach to perform edge detection is presented using an all-dielectric CMOS-compatible metasurface. The design is based on guided-mode resonance which provid…
