Hitoshi OHSATO is a Senior Researcher at Nagoya Industrial Science Research Institute (NISRI), Japan. He received a Dr. of Science from The University of Tokyo in 1984, and a Ms. of Engineering from Nagoya Institute of Technology (NIT) in 1970. He studied at the NIT from 1970 to 2008 as a professor. After retirement in 2008, he joined NISRI and Hoseo University in Korea as Brain-Korea Program Professor from 2009 to 2012. He also studied as a Visiting Scholar in Center for Quantum Device, Northwestern University (Illinois, USA, 1993-1994). His main scientific interests are microwave dielectrics, ferroelectrics and piezoelectrics. He organized the 3rd International Microwave Materials and their Applications (MMA2004) at Inuyama, Japan. His research has been studied consistently electroceramics based on the crystallography. He has published over 285 papers and 14 books, and has filed about 31 patents, which are cited more than 7000 times by the ResearchGate. He has received prestigious awards, including: the 59th Ceramic Society of Japan Award for Academic Achievements (2005), and the 1st Okazaki Memorial Award (2007) from the Fulrath Okazaki Memorial Association. And he was elevated to Fellow of American Ceramic Society in 2016 Annual Honors and Awards Banquet, and he was cerebrated as Nokia Visiting Professor Foundation 2016. And he will got an award for Applied Mineralogy from Japan Association of Mineralogical Sciences (JAMS) 2017. He organized many projects including: Regional New Development Consortium Project by METI (2002-2003) and NEDO (2005-2007).After retirement from NIT, he has been studying Indialite/Cordierite glass ceramics for millimeter-wave dielectrics as one of researchers in Hoseo University in Korea. Now, he has been researching LTCC applied the glass ceramics under Professor Heli Jantunen and was supported by Dr. Mailadil Sebastian in Microelectronics Research Unit in University of Oulu in Finland.

Abstract

Conventional and well-studied techniques such as gel casting and ceramic route to fabricate dielectric substrates have ruled in the last few decades. All of these have the bottom-up approach, which has its limitations when the... [ view full abstract ]
