July 2018: Dr S. Ragahavan writes to tell us about one of the attendees of his recent workshop.  "ONE LADY MICROWAVE PROFESSOR, MUTHU RAMYA has awonderful unbelievable CRAFTS @ ARTS hobby. Will you be interested to post the same in NITT WEBSITE of MICROWAVE 101. She attended the 'MICROWAVE WORKSHOP'conducted by me in NITT . She teaches MICROWAVES in a near by Engineering college."  We're happy to help, sir!  The website is

June 2018: ITT Workshop on CAD of Microwave Integrated Circuits, 9 - 10 June 2018, Tiruchirappalli, India

The objective of the course is to impart in-depth knowledge in the Computer-aided design of Microwave components including antennae through the conventional coding (MATLAB). The highlight of the workshop is to compare the joy and originality of getting the solution through conventional coding with that of commercial software tools (ADS, HFSS, CST MWS, COMSOL, etc.). Each has got its own exclusive merits and demerits. The demonstrations will speak of the above claim. Eligibility: The programme is open to the Research Scholars, UG, PG, faculty members, and Industry persons, to get exposed to the state-of-art design of MICs.

Important note: deadline to apply is June 6, 2018! CAD of Microwave Workshop

Update November 2015: Join NITT faculty and students for a conference entitled "Microwaves Through Software" at NIT Tiruchirappalli (Trichy) on November 6th and 7th, 2015. Read the brochure below:

Microwaves Through Software Workshop (6-7 November 2015)

Here is a "electronic souvenir" from the MTS conference that provides a summary, worth a look if you were there or not:

New for August 2015: an update from Dr. Raghavan on his microwave students and sad news from India.

Below, the MICROWAVE Group of National Institute of Technology Trichy, India has paid respects to the Space scientist Dr.A.P.J.Abdul Kalam in an unique way. To make his coat appear as natural as it was during his last speech in Indian Institute Of Management (IIM), Shillong, the students used tea powder in the floral decoration. He was the Project Director of SLV_3 in 1980 and had a keen interest in MICROWAVE Engineering.

You have to dream before your dreams can come true.

Dr. A. P. J. Abdul Kalam died on July 27,2015. He served as president of India from 2002 to 2007.  He was a first a scientist, and became a politician later. Over 100,000 people attended his services. He wrote 17 books, including an autobiography you should consider reading to learn more about his life.

New for September 2014: a recent lecture was given by Ms. Seema R. Tirky (first year post graduate) to bring awareness of Microwaves101 web site to other students. Thanks for spreading the word, we hope that Microwaves101 lives up to your expectations! Click the images for higher resolution photographs. On the right, the electronics and communication engineering association office bearers of 2014 are shown.

Also during this month, Microwaves101 offers congratulations to the Indian Mars Orbiter Mission Mangalyaan, that entered orbit on 24 September 2014. Bravo!

Here are some words from NITT regarding this historic mission:

Microwave Group of NITT celebrated the proud victory of Mars Orbiter Mission

All health parameters of the Mars Orbiter Mission (MOM) are normal and the its performance will be as per the computed time” said the proud scientist and the project Director of MOM S. Arunan few days before in NITT during his talk to the Electronics and Communication Engineering association students. His words came true when the whole world witnessed Indian Space Scientists' latest space marvel Mangalyan being put in orbit around Mars at the very first attempt. Along with the whole country, the Microwave group, are jubilant for many reasons. Starting from N. Valarmathi. the Project Director of Radar Image Satellite (RiSAT), P.K. Anuradha, the Project Director of GSAT 12 and finally MOM Project Director Arunan had inspired every student of the department to aspire to become space scientists. The Microwave group headed by Dr. S. Raghavan, Professor, and the ECE department celebrated with great joy and satisfaction.  The scholars and the students had designed the colorful model of the MOM in the form of rangoli. Microwave Engineering has played an active role in the mission. One of the present scholars of the Microwave group, Mr.S. Purusothaman is from the Compact Antenna Test Facility (CATF) of ISRO, Bangalore where High Gain Antenna of Mars mission was exclusively tested for the radiation pattern, gain polarization and isolation before integrating with MARS space craft. The communication systems for the Mars mission are responsible for the challenging task of communication management up to a distance of 400 million km. One student Nitesh Jha from Nepal has told that he feels proud to study in India where extraordinary achievement on space science had happened. Another scholar wished that ISRO should excel NASA in space research.  Other proud comments include , "Super power" is exhibited , at the rate of 11 Rs/km the mission is the world’s cheapest interplanetary mission , "the cost is lesser than  the budget (100 million dollars) of the English movie ‘Gravity’ ", and "I will work hard to become a space scientist’". For any space mission volume and weight are very critical and the biggest advantage of microwave is miniaturization. The group is doubly happy to see the practical usage of Microwave Engineering in the space mission which made India scale high!

29 August 2012

Microwave Group of NIT-T for a change formed ONAM POOKALAM using MICROWAVE INTEGRATED CIRCUIT antennas (ten types of antennas instead of ten rings found in the conventional pookalam viz. fractal antenna, patch antenna, implantable antenna, metamaterial antenna, RF ID, smart antenna, UWB antenna, spiral antenna, Yagi antenna, and sector antenna) chips designed and fabricated by the research scholars. Each small chip antenna has its own significant advantages. This Pookalam made up of small antennas propagate the joy of the integration festival ONAM.

Floral Design, traditionally known as POOKALAM is the hall mark of the colourful harvest festival ONAM. Pookalam that is supposed to please KING MAHABALI is normally consists of ten rings, each representing a god is made during the onam celebration (Atham to Thiruvonam). Flowers like thumba, kekka poovu, chemparathy, thechipoovu, mukkutti, aripoo, hanuman kireedam, and chethi. It sometimes denotes Nakshatram of the day.
