Inverse Prism based on Temporal Discontinuity and Spatial Dispersion
Alireza Akbarzadeh, Nima Chamanara, Christophe Caloz
We introduce the concept of the inverse prism as the dual of the conventional prism and deduce from this duality an implementation of it based on temporal discontinuity and spatial…

Flexible-Resolution, Arbitrary-Input and Tunable Rotman Lens Spectrum Decomposer (RL-SD)
Xiaoyi Wang, Alireza Akbarzadeh, Lianfeng Zou +1
We present an enhanced design -- in terms of resolution flexibility, input port position arbitrariness and frequency-range tunability -- of the planar Rotman lens spectrum decompos…

Frequency Vectoralization and Frequency Birefringence
Alireza Akbarzadeh, Nima Chamanara, Christophe Caloz
In view of momentum continuity at a temporal slab, it is shown that instantaneous switching of an isotropic medium to an anisotropic medium offers the incident frequency a directio…
