چکیده
where is the angular frequency and F/m is the dielectric constant c of vacuum. The contribution of the bulk conductivity ( ) have been here separated to any other sort of losses ( ). The problem of the electromagnetic scattering due to a dielectric slab is briefly introduced. To this aim the model shown in Fig. 1 is considered: a unit amplitude wave is incident on a dielectric slab of thickness inside a waveguide, which is assumed air-filled in the remaining part.

متن کاملDevelopment of A Compact and Low Profile Cavity Backed Slot Antenna Using Microstrip Gap Waveguide Technology
Proof of concept of a cavity backed slot antenna based on inverted microstrip gap waveguide (IMGW) technology is presented. Since the antenna is operating based on the first resonating mode of the cavity, it is more compact compared to the ordinary cavity backed slot antennas in which the second cavity mode is used for radiation. Furthermore, the proposed antenna element introduces lower lo...
