Practical realization of DB unit cell

Recently introduced DB boundary is a hypothetical surface, on which cancellation of normal components of the D and B field occurs. Such a DB surface behaves either as a low impedance surface or a high impedance surface, depending whether the incident plane wave is TE or TM polarized, respectively. Basic EM properties of an artificial surface based on recently proposed DB unit cell in 8 GHz frequency band are investigated numerically in various waveguide environments. Prelimi-nary experimental results of unit cell scaled down to frequency band of 300 MHz are reported.
