Perhaps what was written earlier will help in solving this technical problem to get rid of attenuators and reduce losses.
В инженерной среде, породившей планарные технологии, естественно желание разрабатывать новые виды плоских управляемых антенных решеток вытекающей волны. На русском языке (язык – это опыт прожитых веков) естественно желание разрабатывать среды управления полем в свободном пространстве как...

This is for Russian-speaking engineers who know Micro-CAP 12 in a good environment.
В предыдущей части на простейших примерах показано влияние распределенной связи в решетке радиодеталей на согласование источников...
This is a continuation https://www.eng-tips.com/viewthread.cfm?qid=461144 (On Bragg diffraction in antenna technology).
Many years ago I (radio engineer) was thinking about the task from fig.1, but I forced to change my profession and began drilling wells for water. Over 30 years of drilling...
I read a very interesting discussion https://www.eng-tips.com/viewthread.cfm?qid=327402
I tried in vain to help and draw attention to the new gadget https://www.forumhouse.ru/threads/486848/
Now I'm asking for help. I repeat itself. I was involved in diffraction by a periodic phase array many...
Ближайшее похожее: дифракция света на ультразвуковой волне. Причем, ультразвуковых излучателей несколько, длина волны их излучения и формы согнала правильно управляются.
The closest thing is similar: diffraction of light on an ultrasonic wave. Moreover: there should be several ultrasonic...
I read it.
1. The future of the United States after COVID-19.
The U.S. turns further inward and pulls out of NATO and other international alliances, builds actual and figurative walls, and disinvests in other nations. One could also envisage a future in which America learns a different lesson. A...
New mechanism (gadget).
Sometimes the car must be pulled out of the sand, snow, water or swamp before repair. Sometimes, the length of the winch cable is not enough. We invented, made and used a wedge buckle to quickly connect the ends of the cables by a hammer in 1,..., 2 minutes.
You won't...
The Great Vasyugan Mire, the largest swamp system in the Siberia. Is there such a swamp in America? Russia wanted to build a road through this swamp by 2016.
Features of drilling wells for water in the North of the Moscow region.
1. The aquifer sands and the soil above these sands have many stones. So we came up with, tested, corrected the errors and made many hundreds of pieces of innovative downhole filters that are protected from these stones, and...

Два способа научно-технического развития.
Первый: «Цап-царап».
Второй: «Обретение МГД-генератора во времена Кощея Бессмертного … вдохновили слова служащих ГУНИД МО РФ».
Как правильно?

I ask for examples of the use of perforated slabs in the world. In Russia such slabs were not used, but theses about perforated slabs were written in Siberia. In Russia, I did not find support...
My humble obeisances. You got me thinking.
In the North of the Moscow region there is an abundance of glacial moraine ridges, in the lowlands of which there are swamps as in the picture.
Let's compare the discussed method of construction of a 3-meter-wide road in a swamp with two known ones...
