By using a Fabry-Perot resonant cavity analogy along with the reflection-phase information of the photonic crystal, we predicted defect frequencies of planar defect structures. Our predictions were in good agreement with the measured defect frequencies. Our simple model can also predict and explain double defect formation within the photonic band gap.EnglishBand structureCavity resonatorsCrystal defectsCrystal structureElectric network analyzersElectromagnetic wave reflectionElectromagnetic wave transmissionEnergy gapMathematical modelsMicrowave measurementSurface propertiesDefect formationFabry Perot resonant cavityPhotonic crystalsCrystalsReflection properties and defect formation in photonic crystalsArticle1077-3118
