the invention contemplates attenuator devices having an array of multiple waveguide structures comprising a plurality of horizontally spaced cores (arranged either in co-planar or vertically staggered relation) embedded in the cladding. In such devices, each waveguide is associated with...
The overall dissipation capabilities of these four samples to the incident microwave are further estimated by an attenuation constant (α) [4]. As illustrated in Fig. 5c, all the samples deliver α values with an overall upward trend of increasing frequency. The ov-Nb2O5/CNS composite delivers...
Simple formulae are derived for obtaining the attenuation due to wall losses of proper modes (propagating with exponential attenuation but without change of form) in a rectangular waveguide with constant, scalar, wall impedance. It is shown how the procedure can be continued to higher or...
More specifically, we characterize the\nfrequency-dependent loss of a range of coaxial and rectangular microwave\nwaveguides down to $0.005\\,m{dB}/m{m}$ using a resonant-cavity technique.\nWe study the loss tangent and relative permittivity of commonly used dielectric\nwaveguide materials by ...
We measure and analyze the attenuation constant of commercially available microwave-frequency waveguides down to millikelvin temperatures and single photon levels. More specifically, we characterize the frequency-dependent loss of a range of coaxial and rectangular microwave waveguides down to 0.005 dB / ...
The attenuation coefficient of a rectangular dielectric line enclosed by a rectangular shield is obtained by the use of a rigorous mode-matching method to calculate the required mode field intensity. The cross section of the waveguide is overlaid by a grid, and numerical integration is used to ...

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. The rectangular waveguide (WR 90) technique is used to theoretically calculate the attenuation ...
