Information for the entrance examinations

Department of Electrical Engineering and Information Systems strives to foster talent that can contribute to solving global challenges and creating novel values of technology through inclusion of researchers with a wide variety of backgrounds, including electrical engineering, computer science, physics, material science, chemistry, energy/environmental engineering, control engineering, and space engineering.

In order to open the door to prospective students in a wider variety of backgrounds, Specialized Subject has been renewed significantly in FY2020.

Examinees are requested to select and answer two problems from the following. The time of examination is 150 min for the two problems in total.

1. Electromagnetism
2. Electrical Circuits
3. Information (I)
4. Information (II)
5. Solid-State Physics
6. Control and Electric Energy Engineering
