Theoretical and experimental investigations of silicon surface oriented integrated p-i-n structures as quasi-optical modulators of terahertz frequency range have been done. The problem of double injection into the i-region has been solved numerically, and a possible role of nonlinearity in boundary conditions at injecting junctions is pointed out. Our simulations demonstrate that an effective modulation of terahertz wave beams by Si p-i-n structures can be achieved up to 2-2.5 THz frequencies. Measurements at 400 GHz confirm the results of simulations. A possibility of modulation of picosecond monopulses is also investigated.

Biorthogonal interpolating functions have been applied to electromagnetic field modeling through the wavelet-collocation technique in the time domain, yielding a versatile first-principle algorithm for the solution of time dependent Maxwell's equations with inhomogeneous media. The resulting technique is rigorous and maintains high accuracy, while, by virtue of its sub-gridding capability, significant reduction of the computational requirement has been obtained particularly for the modeling of electrically large dielectric waveguides. The proposed technique has been applied to a two dimensional dielectric waveguide beam splitter, with dimensions typical of optical waveguide systems, and improvement in the computational efficiency has been demonstrated.

This paper shows the transmit diversity (TD) techniques in applications for communication systems. General classification of the TD techniques for both TDMA and CDMA systems is presented. Some very promising TD techniques are characterized, i.e. code division TD (CDTD) and the time division TD (TDTD). Implementation of the pre-RAKE technique in the TD transmitter is discussed. Some performance analysis is also included.

The design method as well as realization examples of the K-band filters and diplexers are presented. In the design process the 3D electromagnetic simulations and circuit simulations are combined. The 3D simulations produce accurate results taking into account all effects resulting from CNC fabrication process like rounded corners of resonators. First the filters and other elements are analyzed and optimized separately in the 3D FDTD simulator then the complete characteristics of diplexers are obtained in the circuit simulator where the distances between the elements are optimized.

The paper is mainly concerned with detection of an accelerating target echo by FMCW radar. The processed signal is modeled as a polynomial phase signal, contaminated either by white or colored additive Gaussian noise. Obtained tests, optimal in the Neyman-Pearson sense, are linked with the maximum likelihood estimation procedures dealt with in earlier papers. An example shows the importance of properly suiting the test to the noise statistics.

For use in an anti-collision car radar system, a 77 GHz 5th harmonic,flip-chip Si-Schottky diode mixer was developed in a hybrid microstrip technology. First measurements show excellent conversion data, down to 22 dB conversion loss at 77 GHz and 10 dBm LO power.

Time domain measurement of complex permittivity and complex permeability is considered. Two methods are presented for measuring. measuring in the 2 to 18 GHz frequency band using a horn antenna and measuring in a coaxial waveguide. Some modifications of measurement scheme for the determination of permittivity and permeability are presented and considered, the required formulas obtained in every case. The measurement results of the complex permittivity and complex permeability for some types of probes are presented.

A simplified method has been established to study the dynamic characterization of the two CPW (coplanar waveguide) discontinuities (open-end and short-end stubs). Analytical formulas, easy to use in CAD, are proposed to calculate the inductances and capacitances of these models. The results are compared with measurements performed in the frequency range 1-30 GHz.

This paper deals with the design and implementation of a very compact microstrip Tx/Rx diplexer for future UMTS mobile terminals. Miniaturised loop-resonator filters have been developed and combined into a diplexer structure, satisfying different constraints such as high electrical performance level (especially, a very narrow bandwidth, low insertion losses and a high out-of-band rejection), or great compactness and compatibility with a standard planar integration.
