Development of a Graphical User Interface for Reflection Loss Calculation in Perovskite-RGO based Microwave Absorbing Composites

Abstract

In this paper, a novel method is investigated wherein the theoretical and mathematical analysis of the perovskite-Reduced Graphene Oxide (RGO) based composite microwave absorber is used to form a machine learning model using linear regression to predict the reflection loss and the effective dielectric permittivity of a selected perovskite compound in an RGO-based composite. At first, the theoretical derivation is carried out to find a mathematical relationship between the reflection loss and the dielectric permittivity of the composite and the cationic radii of the perovskite structure, which is then used to form the base for the machine learning model to directly calculate the microwave absorption characteristics from the atomic parameters of the given composite structure. Linear regression is used for the machine learning algorithm which is verified with an R2 of 0.869 with the atomic radii as the input parameters. The model is further used to develop a Graphical User Interface (GUI) to make the prediction more appealing and user-friendly. The current paper provides a new approach to the integration of theoretical knowledge with advanced computing tools to form innovative predictive tools for current microwave-absorbing materials.

The wave mechanics for microwave absorption film-Part 3: Film with multilayers

“…( 18) reduces to s11(k) or RL(xk-1 -) and the input impedance Zin(k, xk -) reduces to that for WMB or MB. However, the input impedance of WMB or MB are usually applied wrongly to the intermediate layer [43,[56][57][58][59][60][61][62].…”

“…Similar to the hierarchical structures with different interface organizations, multilayer film has been investigated for better microwave absorption [55][56][57][58][59][60][61][62][63][64][65][66][67][68]. Even though each layer k in the film shown in Fig.…”

“…Since there is no suitable theory for the middle layers in the film shown by Fig. 1, the results of MB [43,56,57] and WMB [58][59][60][61][62] are often misapplied to layer k. It should be especially noted that beam bk + 1 is not considered in the conventional treatment of WMB but needs to be considered in layer k. Suitable treatment has been developed here for the first time from transmission line theory. It should also be noted that the flawed QWM should also not be applied to the multilayer system.…”

Wave Mechanics of Microwave Absorption Films: Part 3 - Multilayered Films

“…Similarly, multilayer films, as depicted in Fig. 1, have been explored extensively to enhance microwave absorption performance [56][57][58][59][60][61][62][63][64][65][66][67][68][69]. Although each layer (k) within the film possesses its unique r,k and r,k properties, these are effectively averaged out when all the layers in the film are considered as a whole.…”
