In this paper, we demonstrate the reverse Doppler effect associated with the left-handed medium by a simple transmission line circuit implantation. The left-handed medium is analogized with the composite right/left-handed transmission line at microwave frequency. Virtual moving source is realized in the composite right/left-handed medium by electrically trigged voltage-controlled sequential switching...
In this paper, a new microwave absorbing screen is fabricated with multilayered Fe-SiO2 nanofilms deposited on flexible polyimide substrate. Using the transmission line model, the design of the absorbing screen is optimized. The microwave absorption of the optimized structure is verified by experiments, which are in good agreement with the transmission line analysis. Owing to the electrical and magnetic...
