Published from 1963-1979, the Proceedings of the Institution of Electrical Engineers was a monthly periodical that contained significant and original contributions on electrical engineering, electronics and control engineering. A particular feature was the annual IEE Reviews issue, which contained specially commissioned articles written by specialists that reviewed topics in depth for the professional electrical and electronics engineer.

Receiving and transmitting properties of small grid paraboloid by moment method

  The receiving and transmitting properties of a grid paraboloidal reflector of aperture diameter 2.73λ and f/D ratio 0.395, operating at 410 MHz, are analysed using the moment method. For the receiving situation, with a normally-incident plane wave illuminating the reflector, the distributions of current, obtained in the inner grids only, show a close resemblance to those predicted by the physical optics approximation. It is shown that neither maximum scattered nor maximum total electric field on axis is received at the geometrical focus, but at a point between this focus and the vertex. This result is in agreement with that calculated by the physical optics method for small solid paraboloids of the same f/D ratio. Contours of scattered off-axis fields are also presented in the geometric and true focal planes of the paraboloid as well as in longitudinal planes of such a reflector. In the transmitting situation, the grid paraboloid is excited by a centrally driven couplet feed, positioned at different points along the axis. It is shown that the feed position affects considerably the distributions of current in the feed elements but not in the reflector grids, and confirms that defocusing the couplet feed results in an increased forward power gain.

  The input impedance and the electromagnetic fields of a circular-disc printed-circuit antenna are found. The antenna is driven at an arbritrary point. The present analysis takes into account the radiation through the side wall and the fringe field at the edge of the printed-circuit antenna.
G.T.D. analysis of the near-field patterns of pyramidal horns

- p. 1223 –1226 (4)
  A technique of analysing the principal-plane near-field patterns of pyramidal horns excited in the dominant mode based on the uniform geometrical theory of diffraction (u.g.t.d.)^{1, 2} is presented in this paper. The geometrical-optics field is derived by approximating the horn as a quasipyramidal horn waveguide.⁹ Numerical computations of the near-field amplitude patterns of a typical pyramidal horn based on the g.t.d. technique detailed here well correlate with the measured patterns, justifying the validity of the analysis presented. Further, the analysis presented is valid for any arbitrary field point (located in the principal planes) so that pattern computation is possible in the near field or in the Fresnel zone or in the far field.
Mode spectrum of the modified Goubau line

  The problem of surface-wave propagation over the modified Goubau line, which consists of a Goubau line with an airgap between the conductor and dielectric, is formulated by the boundary-value method. The various modes which exist on the line as well as their cutoff conditions and the specific effects of the airgap are obtained from a solution of the characteristic equation. The mode spectrum for the symmetric and hybrid modes as well as the transverse field distributions for the E₀₀ and H₀₁ modes are also presented. The axial power flow and the attenuation constant are calculated for the dominant mode and the salient low-loss feature may be explained perhaps in terms of total internal reflection or duct propagation phenomena.
Class of optimum m.t.i. filters for clutter rejection

  The problem of optimum design of an m.t.i. system for clutter rejection is considered in this paper. The procedure involves minimisation of the output clutter power subject to the constraint that the average output-signal power over the expected target Doppler range is to be kept constant. Another constraint in the minimisation problem is incorporated, according to which the transfer function of the system has a null at the dominant clutter Doppler frequency f_m, which may often be zero. In this way, the distributed component of clutter is minimised at the filter output while the clutter component at a fixed mean relative velocity is completedly suppressed. With the two constraints specified above, the problem is mathematically formulated as a modified eigenvalue problem. Comprehensive results for the performance of the resulting filters are presented.
