Beyond 8 THz Displacement-field Nano-switches for 5G and 6G Communications

Mihai Adrian Ionescu, Elison de Nazareth Matioli, Mohammad Samizadeh Nikooytabalvandani, Riyaz Mohammed Abdul Khadar, Pirouz Sohi

The rapid progress in high capacity communication systems is reaching extremely high data rates of 100 Gb s−1, which demands electronic switches with cut-off frequencies well above 1 THz. The excellent electron transport properties of III-V heterojunctions ...

Non-local oddities

Romain Christophe Rémy Fleury

Introducing non-local effects to metamaterials increases the complexity of their dispersion relation, which allows carefully designed elastic structures to mimic the peculiar roton behaviour of correlated quantum superfluids. ...

Successive training of a generative adversarial network for the design of an optical cloak

Olivier Martin, André-Pierre Blanchard-Dionne

At the nanoscale level, optical properties of materials depend greatly on their shape. Finding the right geometry for a specific property remains a fastidious and long task, even with the help of modelling tools. In this work, we overcome this challenge by ...

Electromagnetic waves under nonstationary conditions, the connection with parity-time symmetry and studies on resonant systems

Theodoros Koutserimpas

In this thesis, the electromagnetic wave propagation is studied in nonstationary-medium scenarios. The electromagnetic fields under material time-modulation are shown to conserve their momentum but not their energy. The mathematical foundations and analysi ...
