A miniaturized uniplanar metamaterial-based EBG for parallel-plate switching noise suppression
Stuart Barth ; Dept. of Electr. & Comput. Eng., Univ. of Alberta, Edmonton, AB, Canada ; Ashwin K. Iyer

As a demonstration of the advanced surface metallization laser etching, drilling and cutting capabilities possible on the LPKF ProtoLaser U3, this paper details results from a novel one-dimensional uniplanar EBG based on transmission-line metamaterials for parallel-plate noise suppression, and is analyzed using multiconductor transmission-line theory.

Laser Ablation of Thin Films on Low Temperature Cofired Ceramic
Bringing Rapid Prototyping In-House

Productivity. Innovation. Time to market. Day to day, year over year, businesses are forced to make critical R.O.I.-related decisions that impact the future and the bottom line. For a growing number of electronics manufacturers, many of those decisions revolve around whether a function should be performed by an outside contractor or kept in-house. But for many companies in the RF/microwave industry this decision is often concerned with continuing to employ an outside printed-circuit-board (PCB) fabricator for prototype PCBs, or to make a $10,000 to $100,000 investment in an in-house, rapid PCB prototyping machine that may represent a key competitive advantage.
Securing Capital Equipment for Engineers

Machines desired by engineers and technical managers are seen by financial decision makers as investments with inherent risk. By writing an effective business case which details how a desired piece of equipment will save the company money, the chance of purchase approval skyrockets.
