NEW Location: We will meet at the Radisson North Denver Graystone Castle (83 East 120th Ave, Thornton, CO 80233).  The hotel is just East of I-25 on the 120th Ave exit.  Unfortunately, our normal meeting location at the library was already booked for this evening.

Hors D'oeuvres Social: Because the normal library room was unavailable, 3M volunteered to pay not only for the meeting location but also for hors d'oeuvres for the chapter.  Do plan to be there for the Social.  The hors d'oevres will include cheese & sausage display, pork & shrimp eggrolls, baked artichoke dip, chicken satay with cucumber relish, dessert, coffee and iced tea.

Abstract: New electromagnetic absorbing products can provide a simple solution for reducing unwanted RF noise. This sheet-type absorbing product is a composite material with magnetic particles embedded in a polymer. It has good noise attenuation performance from hundreds of MHz to several GHz. These products, with their unique electromagnetic characteristics and flexible means of installation, have already been used in many applications and electronic systems. This seminar will cover the technical background of absorbing materials and evaluation methods. Typical application examples, where sheet-type absorbers can be used in the electronic industry, will be presented.
