“…A simple method is a surface temperature measurement with a radiation thermometer, but the fact that there is a temperature difference from the inside has been investigated in various experiments, and unless this problem is solved, it will lead to incorrect measurement. The temperature and its distribution should be validated with multiple methods, such as internal radiation measurements using an optical fiber, a fiber-grating method that measures the local volume changes of the optical fiber, and temperature dependence of the lifetime of the fluorescent material at the tip [30][31][32].…”

We consider the application of microwave energy to a material. The effects of the electromagnetic field on the material and of the material on the electromagnetic field will be described, focusing on the dielectric relaxation phenomenon of the liquid. The dielectric permittivity of mixtures is discussed by extending Debye relaxation to explain how the material behaves with respect to an electric field. We will also consider the energy that the electric field imparts to the material, both thermally and nonthermally. We will develop this relation and describe what form it should take if there is a nonthermal effect in the chemical reaction field under microwave irradiation.

One of the important points in handling microwaves is that the order of magnitude is decimeter order. Laboratory equipment is not too big for wavelength, so intensity nonuniformity may occur. Another important point is that microwave propagation changes with material parameter changes. To heat material in the planned shape, the consideration with electromagnetism about the equipment and the system will be necessary. Herein, the phenomena which should be considered when a flow reactor is irradiated with a microwave is described.
