Welcome to
Caltech Electrical Engineering

Electrical Engineering (EE) at Caltech has a record of excellence and innovation. Many distinguished leaders in the field over the last century received their training at Caltech. As a discipline, EE has had a huge impact on the technologies that define modern-day life and society. EE at Caltech emphasizes both the fundamentals of electronics and systems, as well as acknowledging the multi-disciplinary nature of the field. Closely allied with Computation and Neural Systems, Applied Physics, Bioengineering, Computer Science, and Control and Dynamical System, it offers students the opportunity for study and research, both theoretical and experimental, in a wide variety of subjects, including wireless systems, quantum electronics, modern optics, lasers and guided waves, solid-state materials and devices, bio-optics and bio-electronics, power and energy systems, control theory, learning systems, computational finance, signal processing, data compression, communications, parallel and distributed computing, fault-tolerant computing, and computational vision.

Substantial experimental laboratory facilities, housed mainly in the Moore Laboratory of Engineering, are associated with each of these research fields.

Electrical Engineering postdoctoral scholar Dr. Haowen Ruan and graduate student Mooseok Jang, who work with Professor Changhuei Yang, Ali Hajimirihave won first place for Best Student Poster Presentation at the Engineering Conferences International (ECI) series entitled “Advances in Optics in Biotechnology, Medicine and Surgery XIV.” Their winning poster demonstrated research in biomedical optics, specifically a novel technique that focuses light inside biological tissue by time-reversing the light encoded through popping of a microbubble. The technique has the potential to enable one to “see” through biological bodies with light. 07.02.15

Electrical Engineering student Kuan-Chang Chen, working with Professor Azita Emami, is a recipient of the 2015 Henry Ford II Scholar Award. Kuan-Chang is a member of the Caltech Mixed-mode Integrated Circuits and Systems Lab (MICS) and is researching analog and mixed-signal circuits and systems. The Henry Ford II Scholar Award is funded under an endowment provided by the Ford Motor Company Fund. The award is made annually to the engineering student with the best academic record at the end of the third year of undergraduate study. 05.18.15

Caltech and Northrop Grumman Corporation have signed a $17.5 million sponsored research agreement for the development of the Space Solar Power Initiative (SSPI). The initiative will develop technologies in three areas: high-efficiency ultralight photovoltaics; ultralight deployable space structures; and phased array and power transmission. "The Space Solar Power Initiative brings together electrical engineers, applied physicists, and aerospace engineers in the type of profound interdisciplinary collaboration that is seamlessly enhanced at a small place like Caltech... We are working on extremely difficult problems that could eventually provide the world with new, and very cost-competitive technology for sustainable energy,” said EAS Chair Ares Rosakis.

To make an exact copy of an object with a 3-D printer, Ali Hajimiriyou must first produce a high-resolution scan of the object with a 3-D camera that measures its height, width, and depth. The most sensitive systems generally are too large and expensive to be used in consumer applications. Ali Hajimiri, Thomas G. Myers Professor of Electrical Engineering, has created a new device called a nanophotonic coherent imager (NCI) that is an inexpensive silicon chip less than a millimeter. The NCI provides the highest depth-measurement accuracy of any such nanophotonic 3-D imaging device. 3-D imaging may be a possible feature in future smartphones. [Caltech story] 04.06.15

Victoria Kostina, Assistant Professor of Victoria KostinaElectrical Engineering, is the newest member of the EE Department.  When asked what excites her about research in information theory she states "I love that it is very basic research, very theoretical. Once we strip away all the particularities of a given problem, we are left with a mathematical model, which is timeless. Once you solve such a problem, it stays there. But at the same time, I like that this work applies to the real world. The fact that it gives us insights into how to improve existing communication systems is a very exciting feature for me."
