communications, wireless control and remote sensing
all require a good grasp of the characteristics of radio
waves and a realistic image of how radio waves are transmitted.
As radio waves are invisible, however, it is hard to
visualize their transmission. Furthermore, the propagation
characteristics of the radio waves are chaotic for the
actual complicated environment. In this program, we
use study materials that help students visualize how
radio waves are transmitted and get a feel for how they
operate, for example, by examining changes in the reflection
pattern for different frequencies when a radio wave
is reflected by a building. We also study improved technology
that conforms to transmission characteristics. The students'
understanding is further deepened by experiential learning,
including analyzing measurement data and making simple
antennas. |
