Research Objective
To design and simulate a 28 GHz 1-bit RIS unit cell or array element with two reflection phase states for 6G wireless communication applications.
System Architecture
The design can use a printed resonant patch or slot element, substrate, ground plane, bias/tuning approximation, periodic boundary setup, Floquet ports and phase-state variations.
Simulation Methodology
Two RIS states are compared to obtain nearly 180-degree reflection phase difference with high reflection magnitude around 28 GHz. Parametric sweeps refine geometry for stable mmWave performance.
Validation Scenarios
- base-case model setup and parameter verification
- main design or control case under rated operating conditions
- parametric change to prove robustness and sensitivity
- comparison with baseline or conventional method
- result discussion for thesis, paper and project-report writing
Expected Graphs and Result Discussion
A complete result section should include the main waveforms, model outputs, field plots or comparison tables needed for engineering thesis documentation. For this project, the important graph set includes:
- reflection magnitude around 28 GHz
- reflection phase states
- unit-cell current distribution
- parametric tuning curves
- array-level beam response if extended
Thesis and Research Extension Ideas
The topic can be extended for journal-style novelty by adding optimization, robustness studies, comparative analysis, hardware-aware constraints or application-specific validation.
- 2-bit phase quantization
- PIN diode equivalent circuit
- finite array beam steering
- RIS-assisted channel gain comparison
