Synthesis of linear antenna arrays [PDF]
IEEE Transactions on Antennas and Propagation, 1976 Synthesis of antenna arrays employing the L_{2} -norm as well as the L_{\infty} -norm is discussed. The approximation in the L_{\infty} -norm is obtained making use of Lawson's algorithm. A general iterative perturbation technique has been evolved for pattern synthesis for the case when the antenna currents alone are varied as web as for the case when ...

Antenna-coupled millimeter-wave LiNbO_3 electro-optic modulator [PDF]
, 1991 The phase-velocity mismatch due to material dispersion in traveling-wave LiNbO_3 optical waveguide modulators may be greatly reduced by breaking the modulation transmission line into short segments and connecting each segment to its own surface antenna.
