Abstract

AbsH-lhe design and experkmtaf fin-for a low-cost easfly fabricated mflffmeter-wave fine scmmer is described. 'HI& antenna wnsfsts of a l-mm X l-mm sificon dieketrie rod with a metal grating @siodic shcture) on the upper surface and pi-rA dfodea mounted on the sidewalf. Anarrow 8°beamis radiated from the grated @rturb@surface atan angle dependent on the guide and pwturbalion spacing. Ihe beam angle Ls switckd over a 10°angle by application of a de forward current thmogh the p-in diode nmdufatra9.

The Millimeter Wave Radiation of a Dielectric Leaky-Wave Antenna Coupled with a Diffraction Grating: Broad-Face Interaction

“…In this structure, bound surface waves (slow wave) interacts with the periodic diffraction grating and some part of this wave transforms to the volumetric propagating wave (fast wave). This type of structure can be classified as a leaky-wave antenna [3,4] in general and dielectric leaky-wave antenna (DLWA) [5][6][7][8][9][10][11][12][13][14][15][16][17] in particular. There are examples of DLWA in the literature.…”

“…There are examples of DLWA in the literature. Inverted-strip DLWAs [5,6] and periodically metal-strip loaded DLWAs [7][8][9][10][11][12][13][14][15][16][17]. In those examples, the dielectric image line was in contact with the grating and the grating had a discrete form.…”

The Use of the FDTD Method for Electromagnetic Analysis in the Presence of Indepedently Time-Varying Media

“…The FDTD prediction (·····) is compared to the analytical prediction [1] (---). Using expression (3)(4)(5)(6)(7)(8)(9)(10)(11)(12). lengths" by Morgenthaler [9], who gives an approximate expression for computing them.…”

“…There have already been a number of publications [2][3][4][5][6] describing the realisation of tunable components using bulk distributed properties directly rather than semi-lumped active components. We use the word "tunable" since the variation of the material properties is on a time-scale that is several orders of magnitude "slower" compared to the signal being controlled.…”

Simple estimation formulas for rectangular dielectric waveguide single‐mode range and propagation constant

“…They have been shown to be useful in phase-shifting, optical coupling, material measurements, and antenna applications at these frequencies [1][2][3][4], and they may be scaled in size by changing the material dielectric constant r .…”
