“…However, in view of the ubiquitous requirements of non-line-ofsight (NLOS) transmission with strong fading caused by various metal components in narrow, compact and closed metal spaces, traditional radio frequency (RF) or optical wireless communication technology is faced with great challenges [8][9][10] . As a solution to this problem, the method of capacitive coupling communication within a metal cabinet is becoming an appealing technology 7,11,12 . Capacitive coupling communication was firstly proposed by Zimmerman 13 , and was widely used in human body communication to realize the data transmission between wearable devices or implantable devices using electric field coupling [14][15][16] .…”

An increasing number of various sensors in metallic environment such as vehicle, spacecraft and industrial equipment has contributed to the application of capacitive coupling communication technology, which is considered to be more useful compared with wired communication or traditional wireless communication. In this study, the composition and structure of the communication system were proposed firstly. Then the channel transmission characteristics with different electrode parameters were obtained using finite element simulation model. Moreover, vector network analyzer was used to test the path loss for verifying the simulation findings. The experimental results are consistent with the simulation results, and showed that the transmission gain of the system varied with the electrode parameters. This study can provide theoretical foundation and experimental support for capacitive coupling communication in a metallic environment, and has great significance for promoting the transceiver design and system optimization in the future research.

“…However, traditional radio frequency (RF) and optical signal transmission in such spaces will sustain complex multipath and occlusion, resulting in a dense multipath effect and significant signal attenuation, leading to a large data transmission error rate [8]- [10]. Consequently, electric field communication, also denoted capacitive coupling communication, was proposed in [11], [12] to realize nonline of sight (NLOS) transmission of various sensors for an invehicle environment, which can also be seen as inside a metal cabinet. The capacitive coupling communication technique is currently widely used in intrabody communication (IBC), such as healthcare [13], entertainment, and in-vehicle scenarios [14], with the advantages of high security and data rate, low energy consumption and carrier frequency [13], [15], [16].…”

The channel model optimization algorithm plays a critical role in novel communication method research. Wireless sensor connections using capacitive coupling communication inside a metal cabinet such as spacecraft are an emerging communication technology. However, channel modeling along with optimization methods have not been systematically investigated. In this paper, a modified artificial immune algorithm (MAIA) was developed to optimize a few tens of model parameters for the capacitive coupling communication channel within a metal cabinet. The mathematical model of the communication channel was derived from the equivalent circuit model by analyzing the capacitive coupling electric field distribution. Unknown parameters in the model were optimally estimated by adopting MAIA with the objective of minimizing the root mean square error (RMSE) between the model computed data and simulation or experimental data. The proposed scheme enhanced the convergence performance by incorporating the artificial bee colony (ABC) algorithm, modifying the strategies of immune operations and introducing a similarity detection step. Validation results showed that the frequency response of the optimized model matched well with the simulation and experimental data, verifying the feasibility and robustness of the proposed MAIA. Compared with three other state-of-the-art ABC algorithms and three enhanced intelligent algorithms, it was demonstrated that the proposed algorithm performed better with respect to convergence speed and accuracy. The study provided a multiparameter channel model estimation solution for capacitive coupling communication within a metal cabinet research.
