Computer Simulations of Multiband Waveguide Filter on Modulated Metasurface
P. 1–4.
The paper presents the results of computer simulation of electromagnetic wave propagation in a segment of rectangular waveguide that has one of its wide walls made in the form of a mushroom-shaped modulated metastructure. We used electromagnetic simulation program Ansoft HFSS to obtain the field distribution, characteristics of the complex transmission coefficient S 21 and VSWR associated with fundamental mode H 10 . The results indicate that it is possible to create multiband waveguide rejection filters with improved characteristics and parameters using proposed structure.

We examine the probability of the appearance of high values of the intensity I of a light beam at its propagation
in the turbulent atmosphere. Starting from the functional integral representation of averages over turbulent
fluctuations, we find the saddle-point configuration in the functional space corresponding to the high values of
I. The saddle-point configuration determines the tail ...

It is not a trivial task to develop an effective overhead power line short circuit sensor while being restricted on weight, dimensions, power consumption, and the relative position of the sensor and the power line wire. Traditionally, a current transformer similar to a Rogowski coil is used as a sensor, followed up by either a ...

The application of conventional transient analysis to find the periodic steady-state solution often results in a long simulation time and hence special purpose means are needed. Unlike the transient analysis the periodic steady-state analysis solves a periodic boundary-value problem. The shooting-Newton method transforms the solution of the periodic boundary-value problem to the solution of sequence ...
