Presented in this work is an essential and basic approach to compute the attenuation of electromagnetic waves propagating through a rectangular waveguides with lossy material sample placed inside the waveguide.
attenuation常见例句 1、Bandwidth Bandpass The range of frequencies that a channel will transmit (i. E. Pass through) without excessiveattenuation.───信道传输使用的(即通过)的频率范围,无额外衰减。 2、In order to solve the problem,the calculation formula of microwaveattenuationconstant and phase con...

The first and second reflections can be seen in the dashed rectangular boxes of Figure 2, with the first trailing or slightly overlapping with the Rayleigh burst. Figure 3a–c shows corresponding typical measurements on bone specimens. Focusing first on Figure 3a one can see that ...
Obviously there is a great freedom of choice in the selection of the shape of the recesses, which may be round, oval, square or rectangular. However, it has been found that with a view to mechanical strength it is of advantage to select a shape such that the ratio between the lengths ...
3, the second inner cladding region 83 may be referred to herein as a rectangular trench and may have a constant refractive index that is less than the refractive indices of the first inner cladding region 81 and the outer cladding region 85. The trench shown in FIG. 3, for example, may...

Short rectangular pulses of a radio frequency voltage are superimposed on the line voltage, so as to alter the oscillator frequency for the duration of each pulse to provide the signal frequency. The differerence between the local oscillator and signal frequencies must be maintained constant so ...
