1. A Comparative Analysis of Simulation and Experimental Data in Dual-Broadband Anisotropic Cross Polarization Conversion Metasurface

2. Introduction Metasurfaces are engineered structures capable of manipulating electromagnetic waves. They consist of subwavelength elements that enable unique optical properties. Understanding their design and operational principles is essential for evaluating performance discrepancies. This presentation aims to provide a comparative analysis, highlighting key finding and implications for future research. Fig : Metasurface Structure.

PCR : The Polarization Conversion Ratio (PCR) is a parameter used to quantify the efficiency with which a device, material, or system can convert the polarization state of an incoming wave, typically electromagnetic waves such as light or radio waves, to a different polarization state.

5. Future Plans In our work, we are focusing on optimizing the design of a metamaterial unit cell to achieve two key goals: enhancing reflection performance and increasing angular stability. Enhanced Reflection : To improve reflection, we will adjust the geometry and material properties of the unit cell. By carefully tuning the resonant frequencies and the arrangement of resonators, we aim to achieve higher reflection coefficients over a broader range of frequencies, ensuring better performance in practical applications. Increased Angular Stability : Angular stability is critical for maintaining consistent performance across a range of incident angles. We will enhance the unit cell design by introducing symmetric structures and multi-resonant elements. These modifications will help to reduce performance variation when the incident angle changes, making the metamaterial more stable and reliable under different conditions. By fine-tuning these design parameters, we aim to create a metamaterial unit cell that delivers improved reflection efficiency while maintaining stable electromagnetic properties across a wide range of incident angles.
