*:For a certain mode, in a rectangular waveguide, propagation occurs for signals Information are not sufficient to decide O Whose frequency is above the cut off frequency Whose frequency is below the cut off frequency Depending on the dimensions of the waveguide and dielectric O The dominant mode of propagation is preferred with rectangular waveguides * because we can use air as dielectric O it is easier than other modes and leads to smallest dimension of waveguide it is easier than the other modes it leads to smallest dimension of waveguide none of metioned
What is the value of the wave lengths (X) of the light that is absorbed in a material with energy gap * ?of 1.75 eV semiconductor .λ = 0.3 μm. .λ = 0.5 μm. .λ = 0.7 μm. 15 .λ = 1.5 μm.
By doping semiconductors, it is possible to create materials with specifically designed electromagnetic properties for waves propagating within them. The following 1-D plane wave at a frequency of 10THz propagates in a heavily n-doped silicon: Ē = Ẽ ejot = Ēejat e¯jyz At this frequency and the doping level, the conductivity of the medium is o=105 Sm'. The wave loses 3 dB of intensity (power) over a length of 184 nm. Assume the permittivity of the medium is purely real. Find a. the amplitude attenuation constant, a b. the relative permittivity of the medium, &, c. the wave velocity, v
