Streszczenie
In recent years, holographic communication has garnered significant interest among scientists worldwide. This approach offers unique development opportunities in wireless communication by utilizing meta materials and reconfigurable antenna surfaces. The article reviews two technological solutions that led to the concept of holographic communication: the use of meta materials for wireless data transmission and reconfigurable antenna surfaces. It delves into the principles of holographic communication, transferring optical holography principles to the radio band. The possibilities offered by using metamaterials in creating antenna arrays for wireless communication are diverse. These arrays can redirect incoming signals or minimize interfering signal power through controlled reflection or absorption. The development of metamaterial techniques combined with electronic advancements has led to intriguing signal propagation effects.
The article also discusses the classification of materials based on their electrical and magnetic properties, highlighting the potential applications of negative index materials (NIM) and double negative materials (DNG) in telecommunications. Furthermore, it explores the concept of intelligent antenna arrays, emphasizing their role as autonomous elements within telecommunication systems. The discussion extends to the implementation of reconfigurable intelligent surfaces (RIS) or reconfigurable antenna arrays (RMA) for controlling signal propagation characteristics.
Additionally, the article introduces the concept of holographic wireless communication, which aims to restore three-dimensional scenes transmitted wirelessly using holographic antenna technology and electromagnetic signal technology. It emphasizes dynamic interactions with people, objects, and surrounding environments in a three-dimensional space.
