Abstract :
The bandwidth of the reflection coefficients are evaluated for conducting strips on a grounded dielectric and magnetic slab for the use as artificially soft and hard surfaces. The simple and closed form reflection coefficients developed by the authors are utilized in the numerical calculation. The general observation that the hard surfaces realized by using a magnetic material slab have a significantly wider bandwidth than the ones realized by using a dielectric material slab, is numerically confirmed. A simple linear relation between the bandwidth and design frequency for a perfectly hard surface is found for the first time. The calculated results are very important for the analysis and use of artificially soft and hard surfaces
