High frequency and short wavelength
WebAt higher frequencies, wavelengths become shorter, making the job of packing antennas into small devices less of a challenge and allowing capturing a higher level of the signal reaching the antenna. However, signals also are absorbed more in common building materials, foliage, and other objects. WebHá 1 dia · Pes et al. had demonstrated an extended short-wavelength HgCdTe device (λ c = 2.9 μ m) with 450 MHz bandwidth for long-range free-space optical communication [16]. A. Singh et al. analyzed the optimized MWIR energy-gap grading structure to minimize the carriers diffusion lifetime, and the corresponding fall time was about 700 MHz but with a …
