Waveguide Crossguide Coupler, W Band, 20 dB Directivity
Model SWX-753114320-10-3B is a W-band split block crossguide that covers the full W-band frequency range of 75 to 110 GHz. This three port design incorporates a termination load at the fourth port to offer a compact size and low insertion loss. The smaller form factor and lower insertion loss make this coupler better suited for certain applications than the multi-hole directional couplers while providing good directivity. The coupler offers 0.7 dB insertion loss with 20 dB typical directivity. All ports feature WR-15 waveguides with UG-387/U-M flanges.10.

“The technologies now exist,” said Paul Shattuck, company director for Directed Energy Systems. “They can be packaged into a size, weight, power and thermal which can be fit onto relevant tactical platforms, whether it’s a ship, whether it’s a ground vehicle or whether it’s an airborne platform.

The Air Force of the Future: Lasers on Fighter Jets, Planes That Think
“So everything exists today,” he said, “it’s just a question of the desire and when is that going to occur.”
Added Daniel Miller, Senior Fellow for Air Vehicle Science and Systems with Lockheed’s Skunk Works division, “the question is moving from, ‘Do we have the devices?’ to ‘How quickly can we integrate them on the platform?’ The question has changed dramatically on the last decade.”
In essence, it’s no longer a technological problem to make laser weapons work. It’s one of integration at the service level.
Asked flatly if the services came to them tomorrow and asked for a laser weapon in the 30 KW range to be delivered, the two men, along with Robert Afzal, a senior fellow with Laser and Sensor Systems, agreed they could produce a viable weapon for fielding.
That doesn’t mean that giant city-melting lasers are on their way. Right now, the weapons are limited to the 15-30 KW scale; going much further requires figuring out how to deal with atmospheric interference, an issue which becomes more complicated with weapons mounted on airborne systems.
But a 30 KW weapon can still bore a hole through a two inch piece of steel in seconds, said Shattuck, which is enough to disable an incoming rocket or hit the engine of a pickup truck. For the Pentagon, that is particularly key, as it has openly talked about the costs associated with using kinetic weapons to attack small trucks operated by the Islamic State group, commonly known as ISIS or ISIL.
The company has already proven the capabilities of a 30KW weapon with its Athena demonstrator, which last year conducted a series of tests on small unmanned systems from over a mile away. The weapon was able to identify and disable those systems with great accuracy, down to taking out just a leg of a system or blinding its camera.
A number of advancements in recent years have allowed the company to move forward with laser technology, but the biggest one is the movement in fiber-laser technology, which is largely driven from developments in the commercial sector.
The men described the technology as similar to a rack of servers. Once you figure out how to connect them all, you can add more power by adding another server. The same is true for the laser weapons: you add more power slots into the rack and increase its power.

JESD204B over optical fiber enables new architecture for phased-array
radar
Traditional phased-array antennas rely on analog methods to steer the
beam. This article describes how JESD204B over an optical interface
could be used to implement a digital-control architecture in phased-
array antennas, which has the potential to increase beam precision and
reduce transceiver size and lower power consumption.

ابتكر علماء في جامعة آيوا الأمريكية غطاء يمنع اكتشاف المعدات من قبل الرادارات.
وأطلق على هذا الابتكار اسم "الغطاء الخارق" نظرا لكون المادة التي انتج الغطاء منها تتميز بخصائصها الفريدة بسبب تصميمها المتقن وليس بسبب تركيبها.
فيبدو الغطاء كصفيحة سيليكون تحتوي على دوائر مفتوحة يبلغ نصف قطر كل منها 2.5 ميليمتر وسمكها 0.5 ميليمتر.
ويمكّن مثل هذا التصميم الغطاء من إخماد موجات الرادارات الآتية على تردد معين.
ويسمح تمديد المادة الخارقة وما يسببه من تغيير لقطر الدوائر عليها بضبط الغطاء على طول موجة آخر.
وقد أمتص الغطاء في أثناء التجارب زهاء 75% من إشارات الرادارات التي يتراوح نطاقها الترددي بين 8 و10 جيغاهرتزات وهو نطاق تعمل فيه مختلف الأجهزة بدءا من رادارات كشف ذخائر المدفعية ووصولا إلى رادارات أخرى تستخدمها الشرطة لقياس سرعة السيارات.
ويرى الخبراء أن هذه المواد الخارقة ستغطي مستقبلا طائرات وسفنا عسكرية ما يجعلها غير مرئية للعدو.
