PURPOSE: To measure the reflection loss accurately using an inexpensive small- sized apparatus for determining the internal reflection wave of an antenna from the circular locus of actually measured reflection wave vector described by processing he amount of reflection wave loss corresponding to the ...

Therefore, the intrinsic loss of the gradient acoustic metasurface can be regarded as a negligible factor when deal- ing with the interaction between the impinging waves and metasurface structures. Because of the low energy loss, the acoustic surface bounded waves would efficiently interact with the ...

The planar antenna and the lens form the hybrid antenna for coupling the local oscillator and the signal radiation to the HEB [1], [2], [3], [4]. However, the high refractive index of silicon (nSi=3.42) causes a high reflection loss of about 30% which in turn results in a 30% ...

The mean of both curves would follow approximately the free space path loss, but with a significant fluctuation that depends on the link distance and antenna heights. As a consequence, it is essential to model the ground reflection as a deterministic geometry dependent component, not as a random...
