摘要:

AbstractThe design, fabrication, testing, and analysis of a novel tiny microstrip ring antenna is described. A novel analytical technique is developed for the dimensions and operational properties of this antenna. Measured performance data of the ring antenna are presented and compared with calculated results. Very good agreement between theory and experiment was achieved. © 1995 John Wiley&Sons, Inc

摘要:

AbstractThe resonant frequency, reflection coefficient, and axial ratio of three circularly polarized narrow‐band microstrip antennas realized on various substrates are studied as a function of temperature. It is shown that the choice of the proper substrate material is crucial to provide proper operation of an antenna, even in a limited temperature range. © 1995 John Wiley&Sons, I

摘要:

AbstractActive filter structures are proposed using a low‐frequency transversal and recursive approach. Separate studies of the different functional blocks lead to the design of nontunable and tunable original structures for which we present both simulated and measured results in MMIC technology. We also validate a new stability analysis method developed in [1], by comparing the normalized determinant function to the classical recursive approach. © 1995 John Wiley&Sons, I

摘要:

AbstractSome procedures for the regularization of inverse‐scattering problems are evaluated and discussed by using a singular value decomposition of the Green operator. Results of numerical simulations of a cylindrical scatterer are reported to show the limitations and the capabilities of the described methods. © 1995 John Wiley&Sons, I

摘要:

AbstractBased on the concept of area coding, a 2D gray‐scale morphological processor module is developed by the integration of an optical connector and a PROM device. It is shown that the technique is compact in construction, simple to fabricate, and insensitive to environment. © 1995 John Wiley&Sons, I

摘要:

AbstractA formula is derived from first principles, which enables the shape of the varactor tuning curve to be predicted for a waveguide‐cavity Gunn‐diode oscillator. Only three parameters for the varactor / oscillator structure are required to compute the tuning curve throughout the desired operating region. © 1995 John Wiley&Sons,

摘要:

AbstractThe effect of increasing the field of view by partial‐overlap technique was investigated experimentally for both static and moving images. A number of factors, such as binocular rivalry, suppression, image breakup, resolution, and search time were investigated. The experimental results show that the binocular overlap area should be greater than 40% for the display to be comfortable to the eye. Image breakup effect was found to be predominant for static images but negligible for moving images. © 1995 John Wiley&Sons, I

摘要:

AbstractA numerical technique is presented to study the scattering of electromagnetic waves from slot antennas fed by waveguides with arbitrary terminations. The technique employs the method of moments in conjunction with the entire‐domain basis functions to solve the integral equation derived for the field in the slots. The validity and accuracy of the proposed technique are demonstrated by comparing the numerical results to the solution obtained using the finite‐element method. © 1995 John Wiley&Sons,

摘要:

AbstractBy using the Gaussian approximation of the fundamental mode of a symmetric slab waveguide, the splice losses due to simultaneous tilt, offset, and waveguide‐parameter mismatch of single‐mode slab waveguides have been calculated. Very simple formulas have been derived, and numerical examples have been given. © 1995 John Wiley&Sons,

摘要:

AbstractIn comparison to some other chirowaveguides the geometry of the chiral coaxial line offers an additional degree of freedom, namely, the ratio of inner to outer conductor radius. The influence of this parameter on the dispersion characteristics, in particular also of the dominant mode, is investigated in this report. © 1995 John Wiley&Sons, Inc
