The output gratings of the structure asymmetrically such that the output surfaces at the different sides of the subwavelength aperture can support surface waves at different frequencies. The transmission amplitude as measured at the left side is 1,000 times of that at the right side at 16 GHz. At 24 GHz, the transmission measured at the right side is 20 times that of the left side of the structure. Therefore, surface waves are guided into the different sides of the aperture at different frequencies via metallic gratings. The experimental results are in agreement with the theoretical results. © 2008 Optical Society of America.EnglishDiffraction gratingsElectromagnetic wavesFluid dynamicsMetallic soapsSurface wavesWater wavesWavesDifferent frequenciesMetallic gratingsSubwavelength aperturesSurface electromagnetic wavesTransmission amplitudesWavelength aperturesSurface structuremetalarticlechemistrycomputer aided designcomputer simulationequipmentequipment designinstrumentationrefractometrysurface plasmon resonancesurface propertytheoretical modelComputer SimulationComputer-Aided DesignEquipment DesignEquipment Failure AnalysisMetalsModels, TheoreticalRefractometrySurface Plasmon ResonanceSurface PropertiesArticle10.1364/OE.16.019091
