Source: Electra Aero, Inc. For a long time, science fiction movies have imagined aircraft navigating through skyscrapers in a bustling modern city. However, the reality is that cities lack runways for aircraft, and helicopters are too loud and inefficient for mass-market transportation. This is where Electra’s electric Short Take-Off and Landing (eSTOL) aircraft comes in. By mounting an array of propellers along the aircraft’s wingspan, Electra can achieve short take-off from urban rooftops and parking garages. These propellers are uniquely...

If you’ve ever tried to understand the mysteries of wave physics, you may have come across a seemingly elusive phenomenon known as Anderson localization. Proposed back in 1958 by physicist Phillip Anderson, this theory, which earned him a Nobel Prize in 1977, describes how waves behave when they encounter multiple obstacles in a disordered material. Yet despite its potential impact across fields, Anderson localization has largely remained a theoretical concept due to the complexities of confirming it experimentally and the...

Tidy3D Modeling of a Non-Hermitian Photonic System

08 Jun 2023 By Tom Chen
Share On:

The field of non-Hermitian photonics has seen rapid growth in recent years, with new theoretical insights and experimental demonstrations being reported all the time. Recently, the research group led by Professor Yongmin Liu from Northeastern University demonstrated the precise subwavelength control of light by utilizing the exceptional point in a non-Hermitian system. This work achieved the unidirectional propagation of surface plasmon polariton (SPP) on gold film by engineering a non-Hermitian metagrating structure and has led to a publication in Science...

Share On:

The REGENT Seaglider REGENT’s“seaglider” is a fully electric vehicle that utilizes a blown wing and hydrofoils for takeoff from the water, instead of gas powered engines and a hull used by traditional seaplanes. Seagliders are a much more efficient alternative to traditional hopper flights and a much faster alternative to traditional ferry routes. Such an efficient commuter transport will be greatly beneficial for passengers traveling between coastal cities. Design with Detailed Flow Insights While flying in ground effect, the seaglider’s...
