Beaming Clean Energy From Space
10-26-22
Once considered science fiction, technology capable of collecting solar power in space and beaming it to Earth to provide a global supply of clean and affordable energy is moving closer to reality. Through the Space-based Solar Power Project (SSPP), a team of Caltech researchers is working to deploy a constellation of modular spacecraft that collect sunlight, transform it into electricity, then wirelessly transmit that electricity wherever it is needed—including to places that currently have no access to reliable power. "This is an extraordinary and unprecedented project," says Harry Atwater, Otis Booth Leadership Chair, Division of Engineering and Applied Science; Howard Hughes Professor of Applied Physics and Materials Science; Director, Liquid Sunlight Alliance. "It exemplifies the boldness and ambition needed to address one of the most significant challenges of our time, providing clean and affordable energy to the world." [Caltech story]

Hrishika Basava Receives 2021 Henry Ford II Scholar Award
06-02-21
Hrishika Basava, advised by Ali Hajimiri, Bren Professor of Electrical Engineering and Medical Engineering; Co-Director, Space-Based Solar Power Project, is one of four recipients of the 2021 Henry Ford II Scholar Award. Hrishika is interested in many different aspects of electrical engineering, and specifically applications in robotics and aerospace. She does research in inverse design techniques for nanophotonics with Ali Hajimiri. Hrishika has also worked on the Caltech Racing electrical team and has done research on the explosion mechanism of supernovae at the Carnegie Observatories. At Caltech, she has particularly enjoyed taking hands-on project classes, as well as being a teaching assistant in electrical engineering courses. This summer, Hrishika will be interning at Nuro, a robotics company working on a self-driving car. After graduating she plans to pursue higher education and eventually work in the technology industry. The Henry Ford II Scholar Award is funded under an endowment provided by the Ford Motor Company Fund. The award is made annually to engineering students with the best academic record at the end of the third year of undergraduate study.

2018 Watson Fellow
03-23-18
Electrical engineering senior Michelle Wang, working with Professor Ali Hajimiri and Postdoctoral Scholar Alex Pai, has been selected to receive the Thomas J. Watson Fellowship. She will spend a year abroad working on a series of projects related to the augmentation of humanity through machines. "Prosthetics for children need to be flexible, durable, and need to be able to grow with the child so that they don't have to be replaced constantly," she says. "But beyond that, we want to find ways to make them proud of their prosthetics. We don't just want to give them mobility but dignity." [Caltech story]

Ultra-Thin Camera Creates Images Without Lenses
06-22-17
Professor Ali Hajimiri and colleagues have developed a new camera design that replaces the lenses with an ultra-thin optical phased array (OPA). The OPA does computationally what lenses do using large pieces of glass: it manipulates incoming light to capture an image. "Here, like most other things in life, timing is everything. With our new system, you can selectively look in a desired direction and at a very small part of the picture in front of you at any given time, by controlling the timing with femto-second—quadrillionth of a second—precision," says Professor Hajimiri.
