Machine-translated · View original
A lab that studies the electromagnetic environment (EMC) and the visualization and analysis of electromagnetic fields.

AboutAbout the lab
Measuring, solving, and designing the electromagnetic environment
The Xiao Lab studies the electromagnetic environment and EMC (Electromagnetic Compatibility), the electrical counterpart of environmental problems, as well as electromagnetic field visualization, microwave and millimeter-wave transmission circuits, and computational electromagnetics.
The lab works on methods for measuring and evaluating electromagnetic fields near circuit boards, analysis of crosstalk between transmission lines, and numerical methods for electromagnetic fields.
The lab is very active in joint research with companies and has many international exchanges.
The lab carries out its research in collaboration with the Kayano Lab.

The lab mainly studies the electromagnetic environment and EMC, electromagnetic field visualization, microwave and millimeter-wave transmission circuits, and computational electromagnetics. Specific topics include methods for measuring and evaluating electromagnetic fields to find the causes of radiated interference, crosstalk analysis, and numerical methods for electromagnetic fields.
*Illustrative imageVisualization of electromagnetic waves
To find the causes of radiated interference, the lab proposes methods for measuring and evaluating the distribution of electromagnetic fields and power flow near circuit boards.
*Illustrative imageEMC modeling and crosstalk analysis
Using numerical analysis software developed in the lab and commercial electromagnetic field simulation software, the lab analyzes crosstalk between transmission lines and works to clarify the coupling mechanisms.
*Illustrative imageEMC measurement with TEM cells
The lab proposes a measurement device for immunity and emission using a TEM cell with four inner conductors (septa). For immunity measurement, it examines the system configuration and basic characteristics of a method that creates a slowly rotating electromagnetic field inside the cell, and it also conducts experiments with a prototype.
*Illustrative imageNumerical methods for electromagnetic fields
The lab studies the theory and applications of analysis using the FDTD method, the finite element method, the method of moments, and hybrid methods that combine them.
