This study aims to demonstrate the effects of the different boundary conditions on triangular split ring resonator (TSRR)-shaped metamaterials in X band frequency regime. Three different TSSR-shaped metamaterials are designed and simulated in a certain frequency range. TSSR-shaped metamaterials are utilized to show that the use of different boundary conditions may result in completely different electromagnetic responses. Characterization is explained by applying 5 different boundary conditions. To verify simulation results, an experimental study is realized for the unit cell boundary condition. Both experimental and simulation results are complying with each other. For further investigation, electrical energy density and surface current distributions are simulated and discussed.
