Metamaterials are a hot subject in microwave technology these days. Much of the work I see is going on with the design of antenna structures or substrate materials, but the researchers at Duke University have designed and tested a microwave cloaking device that can almost completely "hide" a small structure from microwaves. While this is not new news, they have more recent work going on to apply this technology to sound waves. The Duke cloaking device is a structure made up of copper rings and wires patterned on a fiberglass composite. The structure is designed to route the microwaves around...

So let's get to some good economic news. ABI research is saying that markets for pulsed RF power devices below 4 GHz are expected to show continued solid growth over the next five years despite the current economic turmoil. While the volatility of many global electronics markets is fueled by their association with consumer spending, markets for pulsed RF power devices are supported by quite different priorities. “Many RF power semiconductor manufacturers are on a quest to find markets unrelated to mobile wireless infrastructure,” notes ABI Research director Lance Wilson. “Device prices in wireless infrastructure are falling, and the total...

As with many other industries, the electronics market is suffering from the downturn and several companies have announced layoffs. STMicroelectronics has outlined a major cost-cutting effort, including a plan to shed 4,500 jobs. In total, STMicroelectronics (Geneva) plans to reduce its costs by over $700 million in 2009. The actions are focused on ''resizing'' the company's manufacturing operations and streamlining expenses. The company - which issued a recent warning about Q4 - also reported sales of $2.276 billion in the fourth quarter of 2008, compared to $2.696 billion in the third period and $2.742 billion in the like period a...

The Strategy Analytics (SA) has posted a new Wireless Network Strategies service report, “US Wireless Market Outlook: 2009 Key Trends,” and predicts that US cellular subscriber growth will remain strong despite the economic situation but growth levels will scale back slightly from 2008. US cellular service revenues will also continue to grow, albeit at a slower growth rate of 3.9%, down from 7.5% in 2008. This is consistent with some surveys I have heard about saying that the technology products people expect to continue to buy are cell phones and HDTVs (those products are part of our everyday life and...

While WiMAX dominated the news over the last year or so, LTE will probably be the hot topic this year as deployments start to happen. ABI Research reports that more than eighteen operators globally have announced LTE deployment plans, and the tough economy does not seem to have dampened their enthusiasm. ABI Research estimates that operators will spend over $8.6 billion on LTE base station infrastructure alone . Verizon has announced acceleration of its LTE deployment timetable, bringing the launch forward from 2010 to 2009. Many of the others are looking at a 2011-2012 time frame , by which time,...

As we kick off the new year, we will be posting our thoughts and related news items that discuss economic trends we see in the hope of gaining some insight into the markets that will grow this year as we try to pull out of this recession. This is certainly a time where market focus is more important than ever and targeting growth markets and any other market opportunities that arise will be a key to success. In this type of economic market, we believe that new product development and targeted marketing are two key areas to concentrate on. Strategy...

Kansas State University engineers are helping Peregrine implement its idea of an energy-harvesting radio. This concept could be used to implement bridge structural integrity monitoring with wireless sensors since changing the batteries on hundreds of sensors on each bridge is not practical. Kansas State is developing the energy harvesting radios for Peregrine to be used in these types of applications. Peregrine's UltraCMOS process leads itself well to very low power devices and K-State engineers are looking at the design challenges of a radio system. Although the prototype captures and stores light energy with solar cells, these energy-harvesting radios could be...

In case you did not see this news item, I just thought I had to share it since it is so appropriate for the holidays (Source: Carnegie Institution for Science): If you are still deciding on what to give the woman (or microwave engineer) who has everything this holiday season, then researchers in Washington may have solved that last minute gift problem – microwaved diamonds. Members of Carnegie Institution’s Geophysical Laboratory have used a chemical vapor deposition (CVD) method to grow synthetic diamonds for their experiments. Unlike other methods, which mimic the high pressures deep within the earth where natural...

We receive several technical articles each month about circuits that utilize Defected Ground Structures (DGS) to improve performance. A DGS is where the ground plane metal is purposely modified with a certain geometry (and positioning of that geometry) to enhance performance. They can be used in various circuits with antennas, filters, delay lines, phase shifters, etc. to improve performance such as modifying the band pass/reject characteristics for filters or modifying the slow wave effect for delay lines or phase shifters. While DGS may improve performance, these circuits are highly susceptible to the effects of the packaging since they radiate. Any...

The Auto show is coming to Boston this week, so I am excited to make my annual visit to this event. We get a group together each year and spend several hours salivating over the new cars (especially the exotics) and then have a nice Italian dinner in the north end. Every year I look for more RF and microwave products in cars but hope the severe down turn in the industry does not effect what we will see too much (I am not counting on getting any giveaways this year). RFID is available on the new Ford F150...
