Electromagnetic Reflection and Transmission by Gratings of Resistive Wires

Calculations show that the effect of increasing the resistivity of the wires is to decrease the amplitude of the reflection coefficient and the phase of the transmission coefficient. The sign of the changes in the amplitude of the transmission coefficient and the phase of the reflection coefficient depends upon the amplitude of the reflection coefficient of a geometrically similar grating having no resistance. A numerical example for a typical grating is worked out and several charts are supplied for convenience in computing.
