Professor / Weihua JIANG
Professor JIANG is an influential professor in fields of pulsed power technology and plasma science. Professor received award of the Fellow for Institute of Electrical and Electronics Engineers (IEEE) in January 2014. Professor is very friendly with student, despite of being very busy, Professor always supports student enthusiastically and gives some kindly advice on your research.

Research Content

Pulsed power technology can be meant simply as adding lots of small electrical energy and releasing them together in very short time-nanosecond. Pulsed power is applied in plenty of fields such as military and industry. Here, we are developing pulse generators such as LTD, Marx, SOS, all of which have lots of unique function. Applications of these pulse generator are also being investigated actively for laser excitation, water treatment and killing harmful bacteria. Beside of compact pulse generator, huge and powerful generator named ETIGO-IV, which is considered as only 1 in Japan, is being investigated and developed in this laboratory.

A Day in the Lab

Daily routine begins with Coffee and English-C&E, we can drink coffee freely and watch interesting English content-daily news or anime. C&E is very useful for improving English skill. Then, we will do experiment or read science papers for more understanding or finding new idea for our research. Especially, Professor always encourages student to improve language skill-English and Japanese, which is very useful for our future. Along with research activity, we have lots of interesting events such as seeing cherry blossom, fireworks festival and mountain climbing. Pulsed power laboratory is very interesting and active for us to study and enjoy in.
