👉 Spectrum engineering is the process of designing and manipulating the electromagnetic spectrum to optimize performance for specific applications, such as communication, radar, or sensing. It involves tailoring the frequency, bandwidth, and other spectral characteristics to meet the requirements of a given technology or system. This can be achieved through various techniques, including antenna design, modulation schemes, and the use of metamaterials or photonic crystals. By precisely controlling the spectral properties, engineers can enhance efficiency, reduce interference, and improve overall system performance. Spectrum engineering is crucial in modern technologies like 5G communications, satellite systems, and advanced radar, where efficient use of the spectrum is essential for high-speed data transmission and reliable operation.
