Metasurface Magnetless Specular Isolator
Guillaume Lavigne, Toshiro Kodera, Christophe Caloz
We present a (nongyrotropic) metasurface magnetless specular isolator. This device reflects as a mirror a wave incident under a specified angle in one direction and absorbs it in t…
Magnetless Reflective Gyrotropic Spatial Isolator Metasurface
Guillaume Lavigne, Christophe Caloz
We present the concept of a magnetless Reflective Gyrotropic Spatial Isolator (RGSI) metasurface. This is a birefringent metasurface that reflects vertically polarized incident wav…
General Mapping between Complex Spatial and Temporal Frequencies by Analytical Continuation
Mojtaba Dehmollaian, Christophe Caloz
This paper introduces a general technique for inter-mapping the complex spatial frequency (or propagation constant) and the temporal frequency …
Metasurface Modeling by a Thin Slab
Mojtaba Dehmollaian, Yousef Vahabzadeh, Karim Achouri +1
We investigate the possibility to model a metasurface, defined as a zero-thickness sheet of surface polarization currents, by a thin slab, characterized by a subwavelength thicknes…
On the Use of Electromagnetic Inversion for Metasurface Design
Trevor Brown, Chaitanya Narendra, Yousef Vahabzadeh +2
We show that the use of the electromagnetic inverse source framework offers great flexibility in the design of metasurfaces. In particular, this approach is advantageous for antenn…
Spread-Spectrum Selective Camouflaging based on Time-Modulated Metasurface
Xiaoyi Wang, Christophe Caloz
This paper presents the concept of spread-spectrum selective camouflaging based on time-modulated metasurface. The spectrum spreading is realized by switching the metasurface betwe…
