This is a specialized book for researchers and technicians of
universities and companies who are interested in the fundamentals
of RF power semiconductors, their applications and market
penetration.Looking around, we see that products using vacuum tube
technology are disappearing. For example, branch tube TVs have
changed to liquid crystal TVs, and fluorescent light have turned
into LED. The switch from vacuum tube technology to semiconductor
technology has progressed remarkably. At the same time,
high-precision functionalization, miniaturization and energy saving
have advanced. On the other hand, there is a magnetron which is a
vacuum tube device for generating microwaves. However, even this
vacuum tube technology has come to be replaced by RF power
semiconductor technology. In the last few years the price of
semiconductors has dropped sharply and its application to microwave
heating and energy fields will proceed. In some fields the
transition from magnetron microwave oscillator to semiconductor
microwave oscillator has already begun. From now on this
development will progress remarkably. Although there are several
technical books on electrical systems that explain RF power
semiconductors, there are no books yet based on users' viewpoints
on actual microwave heating and energy fields. In particular, none
have been written about exact usage and practical cases, to answer
questions such as "What are the advantages and disadvantages of RF
power semiconductor oscillator?", "What kind of field can be used?"
and the difficulty of the market and application. Based on these
issues, this book explains the RF power semiconductors from the
user's point of view by covering a very wide range of fields.

The principal aim of this book is to introduce chemists through a
tutorial approach to the use of microwaves by examining several
experiments of microwave chemistry and materials processing. It
will subsequently enable chemists to fashion their own experiments
in microwave chemistry or materials processing. Microwave heating
has become a popular methodology in introducing thermal energy in
chemical reactions and material processing in laboratory-scale
experiments. Several research cases where microwave heating has
been used in a wide range of fields have been reported, including
organic synthesis, polymers, nanomaterials, biomaterials, and
ceramic sintering, among others. In most cases, microwave equipment
is used as a simple heat source. Therefore the principal benefits
of microwave radiation have seldom been taken advantage of. One
reason is the necessity to understand the nature of
electromagnetism, microwave engineering, and thermodynamics.
However, it is difficult for a chemist to appreciate these in a
short time, so they act as barriers for the chemist who might take
an interest in the use of microwave radiation. This book helps to
overcome these barriers by using figures and diagrams instead of
equations as much as possible.
