Surface Susceptibilities as Characteristic Models of Reflective Metasurfaces

Karim Achouri, Shourya Dutta Gupta, Ville Tuovi Tiukuvaara

While metasurfaces (MSs) are constructed from deeply subwavelength unit cells, they are generally electrically large and full-wave simulations of the complete structure are computationally expensive. Thus, to reduce this high computational cost, nonuniform ...

Metasurface Near-Field Measurements with Incident Field Reconstruction Using a Single Horn Antenna

Shourya Dutta Gupta, Ville Tuovi Tiukuvaara

Metasurfaces (MSs) are the 2-D equivalent of metaterials, the latter being a class of artificial engineered materials exhibiting peculiar electromagnetic properties [1], [2]. Generally constructed as arrays of deeply sub-wavelength resonant particles on a ...

Optocoupling in CMOS

Edoardo Charbon, Shourya Dutta Gupta, Myung Jae Lee

For on-chip data communication with galvanic isolation, a monolithically integrated optocoupler is strongly desired. For this purpose, silicon (Si) avalanche mode LEDs (AMLEDs) offer a great potential. However such AMLEDs have a relatively low internal qua ...
