Quarter wavelength theoryIt is of great significance for absorber designers to correctly understand impedance matching and its related calculation methods, because excellent impedance matching effect is an important prerequisite for absorber to consume electromagnetic wave (EMW). However, there are some ...
process, it became clear that the direction my work was headed made it difficult to continue to classify it as strictly transmission line theory and design. I felt that the best way to present and maintain this ongoing study of quarter wavelength enclosure design was to construct my own web...
