Diffraction Pattern of a Slit in a Thick Conducting Screen

Electromagnetic Transmission through a Filled Slit in a Conducting Plane of Finite Thickness, TE Case.

“…The final formula for power gain agree well with the same example computed in [4] . This case was also experimentally measured in [9) with slight discrepancies in the magnitudes of the sidelobes and nulls when compared with our results.…”

Electromagnetic Transmission through a Filled Slit of Arbitrary Cross Section in a Conducting Plane of Finite Thickness.

“…This integral is broken up into four parts and after similar transformations as used in (3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19), one obtains…”

“…(2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16) and (2-1 7). Explicit formulas will be derived here for these symmetric products using the definit ions of the operators given by Eqs.…”

“…Equations (3-il) and (3)(4)(5)(6)(7)(8)(9)(10)(11)(12) are computed using the electric field operator defined in Eq. (2 -6), from which one obtain s 26…”

“…These solutions are usually valid when the radius of the circular aperture or the width of the slot is small compared to the wavelength . The effects of wall thickness have also been measured for some waveguide coupling problems [5], and for a long slot in a thick screen [6,7,8].…”
