GHz nanoscale electrical and dielectric measurements
of the solid-electrolyte interphase
and applications in the battery manufacturing line
The electromagnetic field is considered one of the fundamental phenomena in nature, as it plays a major role in determining the internal properties of most objects encountered in daily life. Many new technologies are developed owing to extensive research on electromagnetic interactions. Without them, we would not be able to develop advanced medical diagnostics, heat up food in the microwave or use Wi-Fi in our smartphones. Having a general knowledge of the electromagnetic field allows us to better understand the reality around us. 

To promote such knowledge, QWED has developed a stand-alone easy-to-use application for visualising basic electromagnetic phenomena associated with plane wave and cylindrical wave propagation in free space. For plane waves, reflections from and transmission through material interfaces are also modelled. Counter-inuitive effects of full (reflection-less) transmission through dielectric material slabs (under specific thickness-to-wavelength conditions) are illustrated.

The application comes with a dedicated manual, starting with a brief recap of the Maxwell equations and their simplified forms for 1D and 2D problems. Examples of wave propagation in free space as well as half-wavelength and quarter-wavelength transformers are described. The examples are provided in parameterised versions. The application allows setting new parameter values through a convenient dialogue.
Wave propagation – quarter wavelength transformer, 2nd medium width=0.75.
2D problem – 3D graphical visualization.
