Analysis of S-band Microwave Propagation in a Closed Metal Chamber

In this work, signal propagation problem inside a metal structure is studied to explore the possibility of replacing the communication cables of aircrafts by wireless technology. To study this problem, a 3-dimension structure is modeled and simulated using full-wave method. The major difficulties are strong standing wave and small apertures which has a cutoff frequency higher than the employed spectrum. This problem is solved when the aperture is enlarged enough.
