....have been discussed by a number of authors [4, 6, 7, 22] In most THzTDS systems, two distinct lens designs have been widely used, both borrowed from earlier microwave and millimeter wave techniques. In one, the collimating lens, the emitter is located at the focus of the substrate lens [23]. In the other, the hyperhemisphere, the emitter is located so that a minimum of the emitted rays are lost to internal reflection inside the lens [17] This latter design produces a beam with no spherical abberation or coma, and is therefore aplanatic. Although both lens designs have been used ....
....surface of the substrate lens, generally not precisely half of a sphere because of the finite thickness of the substrate and the displacement of the antenna from the lens center. The factor in the square brackets, known as the inclination factor, depends on the inwards pointing surface normal n [23]. This formalism makes a number of simplifying assumptions. First, the vector nature of the field is neglected, so no information about the polarization of the diffracted wave can be obtained. Grtler et al. have recently noted that a full vector field diffraction theory is necessary in certain ....

....OF THE 3RD EUROPEAN PERSONAL MOBILE COMMUNICATIONS CONFERENCE (EPMCC 99) PARIS, FRANCE) PP. 167 172, MARCH 1999 3 as the channel impulse response at the Rx antenna location. For sufficient small wavelength to object size ratios, geometrical optics and the theory of diffraction can be applied [10]. Tx and Rx are regarded as point sources, and the propagation of electromagnetic waves is described by straight lines called rays. The environment is represented by arbitrarily placeable rectangular objects. The electromagnetic properties of each object are described by a single material ....
