Message
In the 20 century, electric energy became an indispensable energy source for social life, and electronics and information and communications became essential technologies for creating a smart society. In the 21 century, electric and electronic technologies will be incorporated into all kinds of goods and services to realize a safe and comfortable life. In the future, mankind will have to solve various problems such as increasing energy demand, the advent of an aging society, and global warming. This requires further technological innovation based on electricity, information and communications, electronics, and functional materials.
There is a need to challenge new frontiers derived from traditional disciplines, as well as further development of traditional disciplines. In order to foster researchers who are free to approach new fields with their own ideas, universities are trying to transform themselves into an environment for creative and flexible education and research.
In order to solve these issues facing society, it is necessary not only to develop existing technologies but also to take on challenges in the boundary areas such as new optical and magnetic properties and sensing technologies. In April 2018, Saitama University Faculty of Department of Electrical Engineering, Electronics and Applied Physics was established through the expansion of the educational and research infrastructure in order to foster engineers and researchers who can master free ideas and face new fields.
Based on this broad perspective, the Department of Electrical Engineering, Electronics, and Physical Engineering (EEAP) is constantly improving its educational curriculum and pursuing new research themes. With the aim of creating a truly prosperous 21 century, we will work together to create a new era through the further fusion and development of electronics and physical engineering.
Department of Electrical Engineering, Electronics and Applied Physics (EEAP)
Electrical and electronic engineering and physical engineering in recent years have become fundamental technologies closely related not only to industry but also to daily life, and the progress of these technologies is remarkable. In order to meet the needs of the times, our department conducts education and research and development not only for electrical and electronic engineering in the fields of power, robots, information and communications, and electronics, but also for functional materials such as new light emitting devices, high-efficiency solar cells, magnetic materials, high-temperature superconductors, and superheat-resistant materials, which are applied physics. We will also develop human resources who can realize an advanced information society by advancing measurement technology that visualizes signals from living organisms and other things that have not been seen before, and information and communications and software technologies that create a smart society by organically linking all kinds of things to information networks. We will also develop human resources who can bring significant benefits to society through the development of control technologies such as robots, new energy sources, and research into efficient energy transmission methods.
In addition to developing excellent human resources who can play active roles in a variety of fields, we will strive to contribute to society by publishing the latest research results.

KADONO HirofumiWe are developing measurement methods using light and conducting research on its application to environmental measurement. In particular, interferometry enables highly sensitive measurement. We are developing the Statistical Interferometry (SIT), an ultra-sensitive optical interferometry based on statistics of the scattered field of laser light. The advantage of SIT is that it can be applied to scattering biological samples, whereas conventional interferometry is limited to specular objects such as lenses. We applied SIT to measure the growth dynamics of plants inavery short time, and studied the response of plants under environmental influence onasecond scale. Asaresult, we have established technology to detect the effects of pollutants such as ozone and heavy metals within minutes to hours. In addition, we use optical tomographic imaging to monitor the effects of the environment on plant interior.

In resistance welding, it is difficult to estimate the internal state because welding and joining are done instantaneously.
